Abstrakt

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.
