The Optimization of the Pass Structure of Double Regenerative Burner with the Numerical Simulation of Thermal Stress Field

In order to solve the problem of cracks of the double regenerative burner, six kinds of low stress pass structures were newly developed and corresponding 3D CAE models were set up. With the FEM numerical simulations of thermal stress field of various combinations of different pass structures and the comparative study, the optimized pass structure that the thermal stress is relatively lower and thus can improve the service life of burner was determined.

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.
