Heat Transfer Enhancement Of Staggered Dimples With Different Shape On Plate

[Full Text]



Dhruv N. Desai, Sanjay N Havaldar



Dimples, Enhancement, Staggered and Inline arrangement, Rate of heat transfer.



Nowadays the most common approach for heat transfer enhancement involves the use of rough surface. A surface can be created rough in number of paths like by using pins, inserting ribs or creating dimples on the surface. With air as working fluid the experiment will be carried out for laminar forced convection conditions. The motive behind the experiment is to find out the rate of heat transfer and air flow distribution on triangle and circular dimples plate with straggled and inline arrangements, and found outcomes are evaluated with flat surface. Dimples 0.64 cm in diameter and 0.30 cm deep on the flat surfaces to enhance the heat transfer rate. Outcomes shows that the rate of heat transfer for triangle dimple shape surface with staggered arrangement seems to have maximum value than the smooth and inline plate.
