Abstract:
Viscous concentric airflow in between two parallel circular discs has been considered. Since the gap in between the plates is small, Prandtl boundary-layer equations were used to explain the flow. In order to solve these equations, the method analogous to Karman-Pohlhausen was used and also a polynomial of the fourth order was assumed for the velocity profile. The coefficients of this polynomial were determined via boundary and symmetry conditions, the integral continuity and momentum equations. The latter is derived from the Prandtl boundary-layer equations.
