摘要：
DLR k-ε turbulence model·BFC method was used to conduct numerical calculation for three calculated examples of turbulent flow on a conical diffuser. The results of calculation showed that the wall value εin,w of the inlet boundary condition of turbulent dissipation ratio had considerable influence on the distribution of longitudinal velocity u over-bar , turbulence energy k and eddy viscosity vt in the centre of flow field but less influence on ε distribution.
