- •
We assess the SST-CCM turbulence model for simulating swirling reacting unsteady flow in a SFRJ.
- •
The impact of the rotation-curvature correction on predicting reacting swirling unsteady flow is demonstrated.
- •
An in-house code to simulate the unsteady swirling reacting flows in a SFRJ is developed.
- •
Experiment on solid-fuel ramjet engine (SFRJ) is carried out to validate the numerical model.
