A reciprocal integral identity of coupled Poisson and Laplace equations in two arbitrary domains sharing a common boundary
In solving the coupled vapor and liquid unidirectional flows in micro heat pipes, we discovered numerically an integral identity.After asymptotic campicon.com and polynomial expansions, the coupled flows yield two reciprocal systems of equations.In system A, a vapor velocity UA obeys the Poisson equation and drives, through an interfacial boundary
