In this paper, the model similarity criteria in wind tunnel test have been confirmed based on dimensionless heat conduction equation, thermoelasticity equations and boundary conditions. The laws consist of ten similarity criteria that must be satisfied between a model and a prototype. Some of the similar parameters were calculated and analyzed. A survey of some available types of test facilities appropriate for these investigations is given. And the results verified the correctness of the proposed similarity criteria. The criteria are applicable and convenient for the wind tunnel experiments to improve the precision and the efficiency of experiment.
