Entransy dissipation of shell and double concentric tube heat exchanger calculations and analysis

الملخص EN

Shell-and-double concentric tube heat exchanger is one of the new designs that enhance the heat transfer process.

Entransy dissipation is a recent development that incorporates thermodynamics in the design and optimization of heat exchangers.

In this paper the concept of entransy dissipation is related to the shell-and-double concentric tube heat exchanger for the first time, where the experiments were conducted using hot oil with temperature of 80, 100 and 120°C, flow rate of cold water was 0.667, 1, and 1.334 kg/m3 respectively and the temperature of inlet cold water was 20°C.

The entransy dissipation rate due to heat transfer and to fluid friction or pressure drop was studied.
