Integral Method of Calculation of a Turbulent Centrifugal Underswirl Flow in a Gap between Parallel Rotating

Краткое описание

A turbulent centrifugal flow in a gap between parallel rotating disks was studied in a special case that the flow tangential velocity at the inlet is less than or equal to the tangential velocity of the disks (flow "underswirl" at the inlet). The equations of a boundary layer were numerically solved by an integral method based on a power approximation of the tangential velocity and a quadratic approximation of the tangent of the flow swirl angle. The unknown variables in the source region were the tangent of the flow swirl angle at the wall and the thickness of a boundary layer, and those in the region of the Ekman-type layers were the tangent of the flow swirl angle at the wall and the tangential flow velocity in the core. The developed method allowed us to achieve significantly better agreement between the results of calculation and the available experimental data than did various method proposed earlier.
