Numerical Calculation of the Comprehensive Heat Transfer Coefficient on the Surface of Rail in the Spray Cooling Process

Abstract

In order to determine comprehensive heat transfer coefficient on the surface of rail in the spray cooling process, the secondary development of the front and back processing module by the Python scripting language for ABAQUS. The Python scripts are written, and cooling curve of rail spray cooling experiment was used to calculate the comprehensive heat transfer coefficient. The results show that Python script can realize the function of automatically creating rail spray cooling model and iterative calculation for the comprehensive heat transfer coefficient under ABAQUS environment. And the time‐varying temperature curve of rail which was calculated by using the comprehensive heat transfer coefficient approximates the experimental value.
