An Analysis on Vortex Instability of Blasius Flow Over Isothermally Heated Horizontal Plates
등온 으로 가열되는 수평 평판위 를 지나는 블라시우스 유동 의 와류불안정성 해석
Abstract
The onset of longitudinal vortices in horizontal Blasius flow isothermally heated from below is studied analytically. The assumption that at the onset of thermal instability the thermal disturbances are confined within the thermal boundary layer is employed for the limiting case of large Prandtl number. Polynomial representations for the basic quantities obtained by the integral method of the boundary layer analysis have been used. Then the system of differential equations and boundary conditions for disturbance quantities is reformulated in a convenient form so that the solutions may be constructed as rapidly convergent power series. The critical buoyancy parameter G
