OpenFOAMを用いた翼型熱交換器の数値解析

抄録

Numerical simulation of convection heat transfer from airfoil-shaped tube by using OpenFOAM. OpenFOAM is a C++ toolbox for the development of customized numerical solvers and processing utilities for the solution of heat transfer. Flow and temperature fields are calculated and compared with those of cylindrical heat tube. Reynolds number based on equivalent diameter and approaching velocity is set to be 10, 100, 200. So the field is assumed to be two- dimensional flow. It is found that the ratio of Stanton number and drag coefficient St/C_D of airfoil-shaped tube is larger than that of cylindrical tube.
