Abstract
The flow inside an axisymmetric diffuser with a curved surface centre body is numerically simulated using different turbulence models, namely a high‐Reynolds number k‐ε in conjunction with wall function turbulence model, a high‐Reynolds number k‐ε with one‐equation turbulence model, a low‐Reynolds number k‐ε turbulence model, a RNG turbulence model and an anisotropic turbulence model. For the separation and reattachment positions, the comparisons made between the various numerical predictions and experimental measurements show that the high‐Reynolds number k‐ε with one‐equation turbulence model is superior to other models in the present study.
