T1 HEAT TRANSFER IN THE RELAXATION ZONE BEHIND LOCAL CLOSED SEPARATIONS JF Heat Transfer Research JO HTR YR 2000 FD 2000-06-01 VO 31 IS 5 SP 326 OP 332 AB The results of an experimental study of temperature and velocity characteristics in the relaxation zone behind separations of various types are presented for the case of low turbulence of an outer flow. A general approach to employment of dimensionless viscosity on the outer edge of a dynamic boundary layer as a parameter which determins intensity and type of separation (laminar, transient, turbulent) is worked-out and widely used at the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine. A method for calculating the heat transfer in the relaxation zone behind turbulent separation is suggested. The data obtained confirm nonadequacy of prediction of the internal structure and different velocities of recovery of thermal and hydrodynamic boundary layers in the relaxation zone.
