註釋
Experimental boundary-layer measurements obtained in a Ludwieg tube used to drive a pilot transonic tunnel were compared with values calculated by a procedure developed by E. Becker and with those calculated by a method containing several modifications to Becker's method. The modifications fall into three general categories: the use of a skin-friction law and velocity profile exponent which are more accurate at high Reynolds numbers; treatment of the momentum equation as axisymmetric instead of two-dimensional; and calculation at a specified location other than at the origin of the centered expansion wave.
