Theoretical study of turbulent mixing in inclined ducted jets

The problem of the inclined plane incompressible ducted turbulent jet mixing with a jet injected into an inclined duct has been analysed using the curvilinear system of coordinates. This system is chosen because of the curved flow field in the initial mixing regions and the existence of similarity solutions when analysed in the orthogonal curvilinear coordinate system referred to the jet centerline. Integral techniques and the similarity solutions have been utilized to reduce the flow field to a quasi two-dimensional flow field. Appropriate differential equations have been developed for the various types of flow regions. A generalized method for predicting the induced secondary flow is presented.
