Rotation influence on heat transfer at supersonic flow around a blunted body K. N. Efimov, V. A. Ovchinnikov, A. S. Yakimov

P. 743-751Abstract: Results of a numerical study of the supersonic high-enthalpy flow over a spherically blunt cone taking into account complicating factors are presented. These factors include simultaneous action of rotation of the body around the longitudinal axis and processes in ablating heat shield. The problem of body heating in a conjugate formulation is solved. At a nonzero angle of attack influence of an aircraft rotation with a small angular velocity (0–500 deg/s) on surface temperature distribution and heat and mass transfer is considered. The asymmetries of surface temperature and material removal via ablation on a rotating body were studied.
