Cluster Design

For the purpose of studying material cluster design and shape design of a certain arc-shaped thermal-protection component rationally, the ablation behavior and thermal stress distribution are studied by using the method of finite element numerical simulation. The study includes ablation tests, numerical simulation of temperature field, calculation of ablation thickness and numerical simulation of unsteady thermal stress field of the component. The simulation results are consistent with the results of ablation tests, which shows that the shape design of the arc-shaped thermal-protection component is rational and the dangerous periods of the component ablation are the time of initial heating and initial ablation boundary retreat.

Set Up

In order to solve the problem of cracks of the double regenerative burner, a kind of new low stress pass structures was developed, and the corresponding 3D CAE model was set up. The results of numerical simulation of thermal stress field of the new pass structure showed that the thermal stress and stress amplitude of the new pass structure is relatively lower and thus can improve the service life of burner.
