Effects of suction/injection and surface curvature on aerodynamically slender bodies of revolution with uniform heat transfer

Controlling the boundary layer has been a topic of interest for a long time due to its practical application, especially in the field of aerospace engineering. In a real-world scenario, it is often needful to prevent flow separation to minimize the drag to get a lift. One of the important methods to control the boundary layer is suction and injection which often give useful information inside the boundary layer. Therefore, the current analysis has been presented theoretically investigating the effects of suction/injection (mass transfer) on aerodynamically slender bodies of revolution generated with a variable radius of power-law shape function. The self-similar flow has been recovered under consideration of some particular form of variable radius that forms a paraboloid body of revolution together with mass transfer velocity and compares the results with those body of revolution that kills the criterion of self-similarity. The particular shapes are considered due to the resemblance of most high-speed aero vehicles to quantify the transport phenomenon along these sophisticated shapes which are considered challenging theoretically in general. The non-similar boundary layer equation is solved with the implicit finite difference technique with second order accuracy, and results are reported through graphs and tables. The impact of convex curvature of the surface has also been highlighted under the mass transfer. The results reported help us to understand the behavior of particular aero vehicles under the heat and mass transfer which can be meaningful for the designing of such practical shapes.
