On a uniformly valid analytical rectilinear cascade response function

A Uniformly Valid Theory of Turbulent Separation

The contribution deals with recent theoretical results concerning separation of a turbulent boundary layer from a blunt solid object in a uniform stream, accompanied by a numerical study. The investigation is restricted to incompressible nominally steady two-dimensional flow past an impervious obstacle surface. Then the global Reynolds number represents the only parameter entering the descripti...

Non-rectilinear Waveguides: Analytical and Numerical Results Based on the Green’s Function

compactifications and function spaces on weighted semigruops

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

Analytical Modeling and Control of Rectilinear Snake Robots

This paper deals with the analytical modeling and control of rectilinear snake robots. During recent times snake robots have created much interest among researchers. The rectilinear pattern gait is one of the four biological snake locomotion modes. Rectilinear snakes have been widely used in rescue operations especially in rough terrains especially in narrow spaces where human intervention is n...

A uniformly valid asymptotic solution for a transverse jet and its linear stability analysis.

An expansion in terms of the ratio lambda of the characteristic crossflow velocity U infinity to jet velocity Uj, where lambda=U infinity/Uj<<1, is used to obtain a representation of the basic three-dimensional steady flow in the nearfield of a transverse jet at large Reynolds numbers and to study its dominant instability. The inviscid vortex sheet analysis of Coelho and Hunt is extended so as ...
