内容如下,
The differences between results obtained with the full potential equation and those obtained with the small-perturbation potential equation are graphically illustrated in Fig.14.9,which shows data calculated by Keyfitz et al.(Ref.106).Here,the pressure coefficient distributions over the top and bottom surfaces of a joukowski airfoil are shown;only the leading-edge region is shown,where 0＜x/c＜0.1(Note that,in contrast to the usual aerodynamic convention,in Fig.14.9positive values of CP are plotted in the upper quadrant.)As described earlier,it is this leading-edge region of the airfoil where the assumption of small perturbations is least accurate.In Fig.14.9,TSD stands for transonic small disturbance(solution of the small-perturbation potential equation as discussed in Sec.14.4),and FPE stands for full potential equation (solution of the full velocity potential equation as discussed in the present section).Also,the solid line in Fig.14.9 represents an analytical solut
