Abstract
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.
