Abstract

An analysis of the turbulent flow in a finite circular gap with a moving wall is presented in this paper. According to Ng-Pan's theory, the linearized equations of motion of turbulent flow were numerically integrated based on the apparent kinematic viscosity method for the evaluation of the turbulent kinematic viscosity, and hence a simple isothermal model neglecting the inertia forces is developed for the study of this particular type of flow. 
Computation methods were developed for the numerical evaluation of the velocity distribution and consequently the volumetric flow rate, the shear stress calculations were considered for the evaluation of friction losses. The computation methods are directly applied to the study of the hydrostatic supports and thrust bearing in turbo machines.
