Heat Transfer Enhancement Techniques with Inserts Different Geometries - A Review

In day-to-day life, we come across many processes where we see the usage of heat exchangers. Some examples where heat exchangers are extensively utilized are air conditioning plants, thermal power plants, food processing plants etc. The basic requirement in these industries is to utilize the heat energy used in the heat exchangers efficiently. This can be done either by developing new designs that are energy efficient or by modifying the present designs in such a manner that they give better performance under the same working conditions. Hence, heat exchangers that would provide more heat transfer at the minimum size and cost are requirement of the present industries. Hence they use the various heat transfer technique for enhance the heat transfer rate. In this paper review of research work in last decade on heat transfer enhancement.
