The calculation of the three-dimensional boundary layer at the turn of the flow on the circular sector

Abstract

The considerable range of problems, connected with the motion of the flow in the flowing part of flying machine engines, is connected with the possibility of the boundary layer equation integration along the complex surface with transverse pressure gradient. For the choice of the solution method and for the construction of the calculation algorithm the three-dimensional boundary layer (TDBL) momentum's equations system need to result in a form which is defined on variables and permits one to conduct both the numerical integration in the common case and analytical analysis in individual cases.
