Twodimensional resisted flow
Abstract
A model of twodimensional, 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 powerlaw 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.
