Abstract
IN HYPERSONIC CRUISE, THE OUTER SURFACE OF A VEHICLE MADE OF A COMPOSITE MATERIAL ABLATES. THE ABLATED PARTICLES PENETRATE INTO THE BOUNDARY LAYER AFFECTING THE FLOW DYNAMICS AS WELL AS RADIATIVE AND CONVECTIVE HEAT TRANSFER TO AND FROM THE VEHICLE. THE AUTHORS PROPOSE TO PERFORM THEORETICAL ANALYSIS OF RADIATIVE AND CONVECTIVE HEAT TRANSFER IN A TURBULENT BOUNDARY LAYER OF HEAT RADIATION SCATTERING AND ABSORBING MEDIUM OVER AN ABLATING FLAT PLATE. IN ADDITION TO DESCRIBING THE PHYSICAL PHENOMENA MORE ACCURATELY, THE PROPOSED STUDY IS RELEVANT TO MODELING THE ABOVE-DESCRIBED HEAT TRANSFER PHENOMENON FOR UTILIZION OF RADIATION AS A STRUCTURAL COOLING TECHNIQUE AND INVESTIGATION OF PROTECTIVE OF THE ABLATED SHEATH IN CASE OF A STRONG INCIDENT RADIATION CAUSED BY A NEARBY NUCLEAR BLAST.
