B.C's : ## \psi_{1} = \theta_{1} = 0 ## at both ## y=0## and ##y=1##.
##\nabla^2 = \partial^2/\partial x^2 + \partial^2/\partial y^2 ##
Both ##\psi_{1} ## and ##\theta_{1}## are functions of x and y.
HI
HI! While trying to solve problem in Hydrodynamic stability I have got a system of Two Partial Diffential equations :
Can anyone help me to solve this analytically? Is there any general method to solve system of PDEs?
