二维GEL耦合方法的研究及对爆炸容器的数值模拟
2-D GEL Coupling Method and Its Numerical Simulation on Vessel to Explosion Impact Load
摘要
Abstract
MF PPM (Piecewise-Parabolic Method) code based on Euler method and DEFEL (2-D Finite Elements Code) code based on Lagrange method were coupled according to the pressure and normal velocity consecutive rule. GEL (Ghost-fluid Euler-Lagrange) method was developed. This method has the advantage of performing large strain fluid field while small strain shell, complicated flow and interactions of many objects. A 2-D example was simulated and compared with the results in reference to prove the validity of the coupling code. Simulations on global and ellipsoidal explosion vessel yielded consistent results with experiments, proving that this program was valid to simulate the flow structure loaded by a blast wave from a central charge.关键词
