hi
I want to write code with matlab using dufort frankel method.
two equation exist for this work . momentum equation in x direction for obtaining velocity inside boundary layer. consider gradient of pressure gradient at x direction as zero but in y direction is not zero.
continuity equation for determining velocity inside boundary layer at y direction.
what should i do for finding unknown variable. should i first determine all velocity in x direction by an approximate method like pohlhousen ? if i do that; then i shall believe that some finite difference method like dufort frankel is useless unless it will be used to optimize results obtained by an approximate method ?
Thanks for your time
