TALK=T;RUN(1,1) DISPLAY The case considered is 2d steady, axisymmetric, turbulent non-reacting flow behind a bluff-body flame holder. The flow configuration consists of a 5.4mm diameter methane jet seperated from an outer, annular air flow by a 50mm diameter bluff body. The flow is characterised by reverse flow in the annular air stream and exhibits well-defined fuel and annular air stagnation points along the centre-line. This case has been studied experimentally by Schefer et al (Comb.Sci.&Tech., Vol.56, p101, 1987]) and was the subject of an ASCF Ercoftac CFD Workshop (Org: D.Garreton & O.Simonin, EDF, Chatou, France, 1994).
