甲烷掺氢射流火焰自适应超大涡模拟
Very-large eddy simulation of blended methane/hydrogen jet flame
摘要
Abstract
As a new type of combustion,hydrogen-enriched combustion has high potential for the application of the decarbonization in power equipment.In the present study,an adaptive very-large eddy simulation(VLES)me-thod based on the k-ε model is developed according to the scenario characteristics of methane/hydrogen blended combustion using high-speed jet.On the basis,combining the eddy dissipation concept(EDC),thickened flame(TF)method,finite rate combustion model and flamelet tabulated combustion model,a high-fidelity turbulent combustion numerical method for hydrogen-blended combustion is developed and verified in detail.Numerical simu-lations are carried out for two different types of classical hydrogen-enriched flames.The simulation predictions are compared with the available experimental and numerical data.The results show that the developed VLES-EDC method can accurately predict the strong unsteady combustion process of methane/hydrogen blended flames,and the prediction results of velocity,temperature,etc.,under the two types of combustion conditions have satisfactory accuracy.For the hydrogen enriched combustion,compared with the finite-rate turbulent combustion model,the prediction accuracy of the flamelet combustion model is reduced,and the prediction accuracy under different com-bustion scenarios needs to be verified accordingly.关键词
