Abstract: | The method of matched asymptotic expansions is used to develop a procedure for constructing separationless plane and axisymmetric
diffusers for incompressible high-Reynolds-number flows with a given pressure distribution over the diffuser surface and minimum
friction losses. The problem for the region of interaction between the boundary layer and the inviscid outer flow is numerically
solved and the effect of variation of the on-design flow parameters in the entry section on the diffuser flow parameters is
studied. |
