The book "Correlation Of Skin Friction With Preston-Tube Measurements On A Cone" offers a comprehensive investigation into the correlation between theoretical turbulent skin friction and measurements taken with a Preston tube on a subsonic cone. This publication is aimed at educators, researchers, and engineers working in the field of fluid dynamics. The research, funded by NASA, pursues two main objectives: first, the development of a method to correlate Preston tube pressure measurements within turbulent boundary layers with the corresponding theoretical values of the skin friction coefficient. Second, this method is applied to a ten-degree cone to obtain the aforementioned correlation. The work includes the numerical solution of the conservation equations for mass, momentum, and energy in the boundary layer, as well as the numerical determination of the pressure-free distribution to establish the boundary conditions at the outer edge of the boundary layer. Finally, the Preston tube pressure measurements are correlated with the theoretical skin friction coefficient values using a least squares method.
