Air conditioning/air cooling systems are necessities of the modern urban world. These applications require huge power and have an adverse environmental impact because of the ozone-depleting coolants used. Saving electrical energy for compressors is made possible by redesigning the prime movers. Interdisciplinary approaches such as electrical engineering, mechanical engineering, thermal science, and solar energy produce electrical energy, which drastically saves more energy than the conventional system. This system converts solar radiations to heated steam to heat exchange to convert liquid coolant to vapor to produce a cooling effect using low energy. The experiment is conducted in a 1Ton conventional vapor compression system using a low-power consumption system built with an ‘ejector-based cooling system’ and ‘Scheffler concentrator-based heating system.’ The results reveal that 80% of energy is saved using unconventional interdisciplinary approaches in the subsystem design. © 2021 S Suyambazhahan, Tatek Temesgen, Anita A.

Energy Saving in an Air-Conditioning System Using Interdisciplinary Energy Conversion Approach

The automobile sector has shown a year-on-year growth in terms of vehicles being disposed and revenue being generated. This drives the motive to conduct intensive research in this area to in order to suffice to change in dynamic needs of industries. Material selection and usage in development of automotive parts can be considered as a significant field of opportunity in terms of introducing heterogeneous combinations to achieve enhanced performance in vehicles. Among this, composites have tend to attract a lot of attention, in terms of manufacturing feasibility and the freedom of developing desired mixture of properties. Moreover with the advancements in additive manufacturing and hybrid manufacturing techniques, composites can be processed with more ease to form finished products with upgraded characteristics. Most of the literature in this area has focused on identifying the mechanical superiority of composites over metals (aluminum, steel). However, a comparatively less amount of work has been done on investigating the thermal behavior of composites. Thus, this paper intends to evaluate the thermal performance of a wheel hub developed using fiber-reinforced composite, during braking conditions in an ATV. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Analytical Study of Thermal Stresses Generated in a Carbon Fiber-Reinforced Wheel Hub

Fins are set on the surface of the cylinder to improve the quantity of heat exchange by convection. Addition of fins can increase the heat transfer from the surface by several folds. IC engine is used to generate the mechanical power from chemical energy contain in a fuel which released to combustion of fuel inside the engine. If excessive heat is not removed, engine components may fail due to excessive temperature. Only approximately 30% of energy released is converted into useful work, the remaining 70% must be removed from the engine to prevent engine parts from melting. To determine the heat transfer rate associated with the fin, we must first obtain the temperature distribution along the fin. The variety of fins are available to enhance heat transfer rate including parabolic concave/convex, triangular, rectangular, trapezoidal, circular and so on. But some of the profiles are difficult to manufacture. In this paper, performance of convex parabolic fin was investigated by Ansys software. In the analysis part total five cases of parabolic fin were considered by varying fin base width, tip width, pitch length, number of fins and fin diameter. Temperature variation of all five cases described in this paper were analyzed by using Ansys software. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Performance Analysis of IC Engine Using Parabolic Fin

One of the most important active safety systems in a vehicle is braking system. The cooling of braking system must be considered as brakes are too much heated during hard and continuous braking. Due to which large thermomechanical stresses are induced in it. This affects disc brake rotor's durability and performance of brake system. The objective of this study is to evaluate the thermomechanical properties of three different materials of the disc brake rotor during the braking process. The metals which are under consideration are AISI4140, SS420 and AISI1020. A single identical design model is used in the present analysis so that results of transient thermal and static structural are only influenced by material properties. Transient thermal and static structural analysis is carried out on ANSYS software and based on the results; SS420 is found out to be best material in terms of thermomechanical properties. © 2023

A solar still is a low-cost device for the generation of freshwater. However, the yield of conventional solar still is meagre; thus, the researchers have used various active and passive methods to augment the freshwater production from a solar still. This article reports the various developments in solar stills using TEMs. TEMs are used for heating, cooling or simultaneous heating and cooling purposes or even generating electricity in solar still. Researchers have used the TEMs in solar still with evacuated tubes, parabolic collectors, heat storage materials, heat sinks, heat pipe and finned tanks. The maximum freshwater yield on TECs is eight times more than the yield with the glass. It is observed that with the use of TEGs to produce electricity and using this electricity to produce forced convection, the daily yield is increased by 14%.

A review of the application of a thermoelectric module (TEM) in solar still

Titanium and its alloys have already been widely used as implant materials due to their outstanding mechanical characteristics and biocompatibility. Notwithstanding this, researchers and businesses alike have continued to actively pursue superior alloys since there are still problems which need urgent consideration. One of these is a noteworthy difference in the implant material’s elastics modulus and that of natural bone, which result into an issue of stress shielding. With prolonged use Ti alloys releases dangerous ions. The Ti alloy surface has a low bioactivity, which prolongs the healing process. β-Ti alloys could be used as viable alternatives when creating dental implants. Additionally, β-Ti alloys characteristics, such as low Young modulus, increased strength, appropriate biocompatibility, and strong abrasion and corrosion resistance, serve as the necessary evidence. Ti alloys when altered structurally, chemically, and by thermomechanical treatment thereby enabling the creation of material which can match the requirements of a various clinical practise scenarios. Additional research is needed which can focused on identifying next century Ti alloys consisting of some more compatible phase and transforming the Ti alloys surface from intrinsically bioinert to bioactive to prevent different issues. In order to give scientific support for adopting β-Ti-based alloys as an alternative to cpTi, this paper evaluates the information currently available on the chemical, mechanical, biological, and electrochemical properties of key β-titanium alloys designed from the past few years. This article is also focusing on β-titanium alloy, its properties and performance over other type of titanium alloy such as α titanium alloys. However, in-vivo research is needed to evaluate novel β titanium alloys to support their use as cpTi alternatives. © 2023, The Author(s).

A review—metastable β titanium alloy for biomedical applications

Single-point incremental forming is a versatile process. It is being studied by many researchers and industries because of its ability to form various geometric shapes without the need for specific tooling. In the current research work, numerical and experimental investigation on thinning in parts formed using the incremental forming process is done. The influence of three-process parameters specifically pitch, tool diameter, and feed on thinning (minimum thickness) is investigated. A hemispherical-ended forming tool with an 8 mm tool diameter made of high-speed steel and aluminum blank Al-6061 with 0.8 mm thickness is used for experimental work. Results show that all the process parameters have a major influence on the minimum sheet thickness of formed surfaces. It is observed that small tool and high feed result in improved thickness, whereas the medium value of pitch results in less thinning.

Numerical and Experimental Investigation on Thinning in Single-Point Incremental Sheet Forming

In the present research work, parts are formed using two-step hybrid incremental sheet forming (HISF) process. The effect of process parameters such as preform tool size, tool diameter, and preforming depth on thinning in the formed part is studied. A simulation model is developed and simulation results are compared with the experimental results. Also, results of HISF process are compared with the results of single point incremental sheet forming. The simulation results are in good agreement with the experimental results. It is observed that HISF process results in lower thinning as compared to SPIF process. Further, it is found that preform tool size has considerable influence on the minimum thickness of formed part. Large preform tools result in relatively lower thinning.
