Distribution of the temperature in the coaxial tube heat exchanger with spherical end

Abstract

A solution is presented for flow inside a heat exchanger. An analytical approach is developed and validated with a numerical simulation using ANSYS CFX code module taking account different boundary condition in the inlet. The temperature distribution of the laminar flow is presented, which is related to Reynolds number and the hydraulic diameter of the heat exchanger.
