Two-dimensional resisted flow
Abstract
A model of two-dimensional, incompressible, resisted flow has been developed. The model is applicable to the flows in narrow gaps which occur in leakage and lubrication problems and also to flow in a porous matrix. The resistance is expressed in terms of a friction factor with power-law dependence on the local Reynolds number and the solution method gives the pressure and velocity distributions. Inertial effects are neglected in the model, but its use with a turbulent friction law can in some circumstances be justified at moderately high Reynolds number. The equations are derived in terms of vorticity and stream function for a model retaining the inertial terms. Some features of the vorticity distribution in such flows are described.
