兩面이 볼록한 物體周邊에 形成된 非壓縮性 層流 境界層內의 剝離現象에 관한 數値解析的 硏究 = Numerical Method of Separation in Incompressible Laminar Boundary Layer Formed Around Symmetrical Biconvex Body

다국어 초록 (Multilingual Abstract)

The object of this study was to find the separation point through Numerical Method, which happened at lower surface in a two dimensional incompressible laminar boundary layer formed around symmetrical biconvex body at angle of attack. It was assumed that a half thickness of biconvex body was unit length. A chord length was varied 20, 60, 100, 200, 400, and an angle of attack was varied from 0 degree to 45 degree.
In order to obtain solutions finding the separation point, Momentum equation, continuity equation and Bernoulli's equation were combined and the corditton of separation was found. Equation of Velocity distribution around biconvex body given by Van Dyke was substituted to this condition and solution on each variables were obtained.
The result was that seperation point happened at the more back of model as chord length and angle of attack were more increasing.
