QUASI-VARIATIONAL PRINCIPLE FOR THE VORTEXPOTENTIAL FUNCTION OF ROTATIONAL FLOW IN THREE-DIMENSION PIPE

The variational analysis of the Pseudo-potential function-vortex-potential function model, a new mathematical model, was developed and by which the flow field with transonic speed and curl was decided, and different sorts of the variational principle for vortexpotential function were established by transforming the original equation for vortex-function, the boundary conditions for vortex-potential function was raised.
