a 1 = (0.05b -0.075b +D.025b 3 )/D

The total flux near the cavity is 



f 



(V -V „) dx = mx 

 nu nil 



mx is the flux of the corresponding wedge (or uniformly distributed V up to x), 

 That is 



!a 2 I 



(2a../x +a„x+ y- x J - (2a vx + a„x+a„ -x~ L /x 



This is the same as the leading edge cavity thickness at x 



I >. -± +a 2 + / x ) u - ( 2 -± +a 2 + / x ,,
