Flow Passage

Rotational and three-dimensional terms are added to a strip-integral method for predicting the behavior of turbulent boundary layers. The secondary flow in the boundary layers is analyzed, and a theory for the momentum transport in the corner regions is used to couple the development of all the boundary layers. Simple assumptions for the potential flow and wake regions complete a model which allows the calculation of the whole channel flow, with only the specification of the inlet boundary layers.

Boundary Layer Growth

An integral method for computing turbulent boundary layers on rotating disks has been developed using a power law profile for the tangential velocity and a new model for the radial profile. A similarity solution results from the formulation. Radial transport, boundary layer growth, and drag on the disk were computed for the case of a forced vortex frees tream flow. The results were compared to previous similarity solutions. The method was extended to a Rankine vortex freestream flow. Differential equations for boundary layer parameters were developed and solved for different Reynolds numbers to look at the net entrainment, boundary layer growth, and drag on the disk.

The Cross

A family of hodograph models for the cross flow velocity component of three-dimensional, turbulent boundary layers is presented. The principal advantage of this family is its flexibility which allows a wide variety of possible shapes for the hodograph. An integral method based on this family is developed and applied to data obtained in curved, rectangular channels. For the cases treated, the method gives acceptable results for cross flow profiles with and without flow reversal. Suggestions for refining the method are given.
