ENGINEERING PREDICTION OF TURBULENT SKIN FRICTION AND HEAT TRANSFER IN HIGH-SPEED FLOW

摘要

A large collection of experimental turbulent-skin-friction and heat-transfer data for flat plates and cones was used to determine the most accurate of six of the most popular engineering-prediction methods;the data represent a Mach number range from 4 to 13 and ratio of wall to total temperature ranging from 0.1 to 0.7. The Spalding and Chi method incorporating virtual-origin concepts was found to be the best prediction method for Mach numbers less than 10;the limited experimental data for Mach numbers greater than 10 were not well predicted by any of the engineering methods except the Coles method.
