Arrangement of tubes plays an important role in many engineering applications like in heat exchanger, radiator, evaporator, nuclear power plant and thermal power plant. Type of arrangement and tube spacing are decided on the basis of the Fluidelastic instability, but the phenomenon of vortex induced vibration is random in nature. Tube spacing also plays a critical role in different types of arrangement. Tube spacing differs for different type of application and the range of tube spacing vary is from 1 to 6. Vortex Induced Vibration in cross flow around the inline and staggered arrangement of the tube arrays is experimentally studied for varying P/d (tube spacing) ratio. It is observed that with the increase in the velocity, the amplitude displacement increases. As the pitch over diameter ratio is increased from 2 to 4, the amplitude displacement of the tube reduces. It is also observed that between inline and staggered arrangement, the amplitude displacement of staggered arrangement is more compared to inline arrangement for same tube spacing.
