摘要

研究了模拟固体燃料冲压发动机非定常反应旋涡流动的有限速率模型与涡散模型的区别。开发了一个内部代码来求解具有化学反应的可压缩流场的控制方程。对该代码进行了验证和验证，并应用于高密度聚乙烯固体燃料冲压发动机的非定常仿真。结果表明，两种模型的性能相似，但在非预混火焰(扩散火焰)燃烧室中，有限速率模型优于涡流耗散模型。

Combustion modeling of unsteady reacting swirling flow in solid fuel ramjet

The differences between finite-rate and eddy- dissipation models for simulating unsteady reacting swirling flow through solid-fuel ramjet engine are investigated. An in-house code has been developed to solve governing equations of compressible flow field with chemical reactions. The code is verified, validated, and then used to perform unsteady simulations on solid-fuel ramjet engine with high-density polyethylene. The results showed that both models are act similar, however, finite-rate model is preferred in such combustors with non-premixed flames (diffusion flames) over eddy-dissipation model.
