Abstract The flow field inside the combustor of a scramjet is highly complicated
and the related turbulent Prandtl and Schmidt numbers have a significant impact
on the effective numerical prediction of such dynamics. As in many cases
researchers set these parameters on the basis of purely empirical laws, assessing
their impact (via parametric numerical simulations) is a subject of great importance. In the present work, in particular, two test cases with different characteristics are selected for further evaluation of the role played by these non-dimensional
numbers: Burrows-Kurkov case and DLR case. The numerical results indicate
that More >
