Review on ?Heat Transfer Enhancement Analysis of Flow over the Bumps on Divergent Channel?

Sunil More , Digvijay Shelke

Effective fluid mixing is one of the requirements in food processing and chemical industry. The effect of divergent channels is a good way to promote the flow mixing in channel flow. When if we use divergent channel then we get flow difference means low pressure drop it is also called pressure recovery. By using bump in the divergent channel it can help us to increase the heat transfer enhancement and bump surface present the highest performance of the heat transfer enhancement. The bump surface act as extended surface (fin surface) and the main purpose of extended surface to increase the heat transfer rate. The advantages of the divergent channel with internal Bumps are fluid mixing is more as compared to cylindrical pipe, pressure drop is less and boundary layer separation occurs in divergent channel which will help in heat transfer.
