内燃机燃烧模型的发展现状

利用CFD技术对内燃机燃烧过程进行数值模拟已成为内燃机研究的重要工具。选用恰当的燃烧模型对准确预测内燃机燃烧过程具有重要意义。内燃机CFD燃烧模型主要针对自燃、预混燃烧和非预混燃烧3种燃烧模式，其中有些模型可以同时模拟2种模式或3种模式。内燃机新的燃烧系统的不断出现促进了燃烧模型的发展。本文以STAR—CD和FIRE软件为出发点，介绍了内燃机燃烧模型的发展现状。

Developments in Combustion Modeling in I. C. E

Using CFD to simulate I. C. E combustion process has become an important tool in I. C. E research. Choosing appreciate combustion model serves as major prerequisites for the successful analysis and optimization in I. C. E. The combustion models were built according to the combustion modes of premixed, non-premixed and auto-ignition. The new combustion systems of I. C. E promoted the development of combustion model. Based on the STAR-CD and FIRE software, the development and the application status of turbulence controlled EBU model, a laminar and turbulent characteristic-time model, CFM series models, Weller model, turbulent flame speed closure combustion model, PDF model and shell model were mainly discussed.
