Abstract

The article presents the computational study of a double pipe heat exchanger (DPHEX) with and without inserts in both co-current and counter-current configurations with hot air as the fluid in the inner pipe and cold air as the fluid in the annulus. The velocity of hot air was maintained constant at 4.5 m/s and the that of cold air was varied between 2.7 and 6.6 m/s. The hot air was maintained at 90℃ in the inlet and that of cold fluid at 32℃ in the inlet. Two different inserts were placed in the annulus and their impact on the heat transfer rate, effectiveness and other performance parameters were compared with that of a DPHEX without inserts. The heat transfer rate of DPHEX with continuous insert was found to improve by about 16% than the DPHEX without insert, and about 3 % than the DPHEX with discontinuous insert.
