Аннотация

Fins designed to streamlined shape proved to be excellent replacement to zig-zag channel printed circuit heat exchangers (PCHE). Pressure drop in such streamlined fins is considerably less compared to other types of PCHE. The objective of the present study is to use numerical techniques (Ansys-Fluent®) to predict heat transfer and pressure drop characteristics in two such streamlined bodies. (Fig 1). Numerical results are verified using modified Dittus-Boelter equation for Nusselt number across the channels. Based on the present studies a new model is proposed that maximises the heat transfer effectiveness in PCHE using super critical carbon dioxide (S-CO2).
