Развитие ламинарного диффузорного течения в соосном коническом канале с неоднородным начальным профилем скорости

Abstract

The problem of laminar diffuser coaxial conic flow development was solved in this paper for constant width channel with the nonuniform velocity at the entry. It was shown that for pressure calculation we can use the expression received for stabilized flow, in other words, without entry correction. It was shown that in such flows the boundary lay separation can take place at the external surface of diffuser with the Reynolds numbers which are bigger then 600.
