The velocity potential is (uniform flow, source at z =0, sink at z = e :) so the complex conjugate velocity is: There are two singular points; one at z =0, the other at z = e . Blasius formula is: Expanding W2 : To find the residue at z =0, we can look at each term separately. eva longoria and jesse metcalfefirst baptist valley view txWebThe theorem considered by Blasius (1910) represents a well-known method for calculating the force on a body situated in an incompressible, inviscid two-dimensional flow. The efficiency of the Blasius theorem is due to its quality of expressing the forces with the aid of contour integrals of analytic functions of complex variables. eva longoria and her son
