HYBRID 열교환기 설계와 열전달 및 압력강하 특성에 대한 수치적 연구

Abstract

The aim of the present study to develop the design program of a hybrid heat exchanger using the method. The design program is developed for the design to use easily with the help of GUI, menu program and dialog boxes.

The concept of hybrid heat exchanger is to adopt the merits of both shell and tube heat exchanger and plate heat exchanger. The plate of hybrid heat exchanger is pressed in the shape of elliptical dimples.

The correlations of heat transfer and pressure drop for elliptical dimples are not published. In the present study, the characteristics of the heat transfer and the fluid flow over the dimpled plate are predicted by using the Fluent 6.2. A grid system is got by ICEM-CFD using output file parasolid of 3D modelling of Unigraphics.
