Abstract

Effects of angular rotation of a general or a pre-heated blunt body flying at supersonic speeds on its boundary layer and heat transfer characteristics for various operating and surface conditions are investigated. Information obtained can be used in assisting the selection of optimum rotating speeds for stability reasons and in selecting window surface materials for designing the frontal region of guided projectiles. A mathematical model based on similarity and coordinate perturbation analyses performed on the Illingworth-Stewartson transformation plane is constructed and governing equations of the compressible rotating laminar boundary layer flow are transformed into a set of coupled, nonlinear equations in first, third and fifth order of transformed coordinates. A standard numerical integration scheme is employed to solve the equations and a systematic shooting technique is used to overcome the difficulties introduced by the boundary conditions. Velocity and temperature profiles as well as shear stress, skin friction and local heat transfer rates are directly expressed in terms of the transformed variables. Flow data, flow separation and heat transfer rates can be used as initiation calculation for the corresponding axisymmetric eddy-viscosity turbulent numerical scheme.
