GRADIENT CRITERIA OF TRANSFER RELAMINARIZATION AND FRICTION DRAG IN SUPERSONIC BOUNDARY LAYERS ON FLYING OBJECTS AT HEAT EXCHANGE
要約
Results of flight experiments concerning
transition and relaminarization Reynolds numbers and
heat exchange have discussed; experimental and
calculated wall temperature being compared.
Emmons's theory of turbulent spots (1971) and
asymptotyc theory of S.S.Kutateladze and AJ.Leontjev
(1985) have been applied to real conditions of flowing
around bodies. Method of integration of numerical
calculations and flight tests data is suggested; on the
basis of last one values of gradient stability criteria are
determined in zones of laminar flow, beginning of
laminar-turbulent transition and relaminarization;
friction drag is found.
