Abstract

In this paper, fluid-solid thermal coupled computational models have been set up to simulate the subsonic nearwall airflow traversing a crater in target and heat transfer in target solid without phase transition in order to predict wall shear, heat flux and heat transfer coefficient on target surface and temperature field in the target under laser irradiation. The prototype of the model is the experiment zone of a flow simulation experiment facility, and the model was verified by the measured flow field data in it. The turbulence is modeled with Reynolds stress transport model. Laser irradiation is simulated with a beam of direct irradiation applied to the exterior boundary of the computational domain.
