Hilde Bortier,Lucien C. A. Vakaetoduced by allowing a free jet to impinge normally on a plane surface. A discussion of the phenomenon on the basis of boundary layer theory, for both laminar and turbulent incompressible flow, has recently been given in a paper [.] by the author (1956). For laminar flow it was shown that a similarity

Nicholas R. Lengyel,Mama N. Toure Ep Camara remains not completely solved. Theoretically, the most easily tractable mechanism of transition is that following the development of the disturbances in the laminar motion caused by its inherent instability. When the disturbances are small, the equations describing the motion can be linearized, and

By regarding the right-hand side of (1) as an inhomogeneous term, one can solve the constant-coefficients differential equation that remains, using (2), to get a representation of . in terms of the rig

Allan Warmington,Tom Lupton,Cecily Gribbinused could be applied also to visualize the periodic boundary layer phenomena on steady aerofoils. The method uses the fact that periodic motions seem to come to rest if they are illuminated by a stroboscopic light source, flashing with the right frequency. By introducing smoke into the boundary lay
