Book Description
A viscous inviscid interaction method for three dimensional flows, in which the partially parabolic Reynolds equations are coupled with an inviscid flow solution procedure in an interactive and iterative manner, is applied to two simple three dimensional bodies for which experimental data are available for comparison. The relative merits of interactive and global solution procedures are evaluation by comparing the viscous inviscid interaction solutions with noninteractive large domain solutions of only the viscous flow equations. Both methods yield satisfactory results, although the interaction solutions are found to be computationally more efficient for the cases considered. Keywords: Thick Three Dimensional Layer; Viscous Inviscid Interaction; Partially parabolic Equations; Computational Fluid Dynamics.

Book Description
This is the first book in English devoted to the latest developments in fluid mechanics and aerodynamics. Written by the leading authors in the field, based at the renowned Central Aerohydrodynamic Institute in Moscow, it deals with viscous gas flow problems that arise from supersonic flows. These complex problems are central to the work of researchers and engineers dealing with new aircraft and turbomachinery development (jet engines, compressors and other turbine equipment). The book presents the latest asymptotical models, simplified Navier-Stokes equations and viscous-inviscid interaction theroies and will be of critical interest to researchers, engineers, academics and advanced graduate students in the areas of fluid mechanics, compressible flows, aerodynamics and aircraft design, applied mathematics and computational fluid dynamics. The first book in English to cover the latest methodology for incopressible flow analysis of high speed aerodynamics, an essential topic for those working on new generation aircraft and turbomachinery Authors are internationally recognised as the leading figures in the field Includes a chapter introducing asymptotical methods to enable advanced level students to use the book

Book Description
The study of flows with viscous/inviscid interaction has attracted many researchers over the last decade. These flows occur whenever the adverse gradient is large enough to cause flow separation. The current emphasis is to find efficient ways of solving these types of flows without solving the full Navier-Stokes equations. Three methods for solving the viscous/inviscid problem were studied. The first method uses finite difference equations to model both the viscous and inviscid regions. A coupling scheme is developed to match the two solutions. The second method solves the integral boundary layer equations in the viscous region and finite difference equations in the inviscid region. The third method solves the Hilbert integral to generate a correction to the inviscid velocity using the boundary layer equations as the viscous model. The model problem used in this work is Howarth flow over a flat plate. The three methods were evaluated in terms of solution accuracy, memory requirements, and computation times. Theses. (mjm).
