氢气爆燃转爆轰数值模拟研究进展
Research Progress on Numerical Simulation of Hydrogen Deflagration-to-Detonation Transition
摘要
Abstract
Hydrogen energy safety issues are one of the key bottleneck problems restricting the high-quality development of the hydrogen energy industry.Hydrogen has a wide combustion range,low ignition energy and high flame speed.After being accidentally ignited,it is prone to cause Deflagration-to-Detonation Transition(DDT),resulting in serious accident consequences.The flame velocity and pressure before and after the occur-rence of DDT have a large span and obvious nonlinear characteristics.Therefore,the full-process simulation of DDT has always been a research hotspot and difficulty in the field of gas-phase combustion and explosion.First-ly,the research progress of simulating the hydrogen DDT process based on commercial software FLACS,ANSYS Fluent and GASFLOW-MPI,open-source software OpenFOAM and self-programming methods was reviewed.Through comparative analysis of the advantages and disadvantages of various simulation methods,it was pro-posed that the hydrogen DDT simulation method based on the open-source software OpenFOAM had the greatest application prospects.Supplemented by the Adaptive Mesh Refinement(AMR)technology,it can take into ac-count both computational accuracy and efficiency,and was expected to achieve synchronous application in basic research and large-scale engineering problems.Finally,suggestions and prospects were given for the numerical simulation research of hydrogen DDT.It was pointed out that the integration of Artificial Intelligence(AI)tech-nology to empower the rapid numerical solution of DDT was a research direction worthy of attention in the future.关键词
