摘要
The non-linear k − ε model by Merci et al. (2002a, 2002b, 2003a) is applied to inert and reacting bluff body flows (Dally, 1998). Based on observed shortcomings in the results, the turbulence model is adjusted without deteriorating previous results. The obtained improvements for the bluff body flows are, however, rather limited. Probably, the flows, which are strongly unsteady in reality, are too complex for any two-equation turbulence model to yield satisfactory results throughout the domain. An unsteady calculation seems necessary (TNF, 2003a).
