Abstract : This report presents the results of a survey of theoretical and experimental determinations of the effect of slip flow on skin friction and heat transfer. Both the theoretical and experimental results indicate that for a given axial pressure gradient, slip effects can be correlated as a function of the local Knudsen number based on boundary layer thickness. An approximate method of estimating slip effects is suggested for practical flight shapes having axial pressure gradients. Quantitative evaluation of slip effects for a flat plate and a hemisphere in hypersonic high altitude flight indicates that slip effects are overshadowed by other low density effects such as transverse curvature and viscous interaction between the shock wave and boundary layer.
