| Abstract: | The authors have studied the non conforming mixed finite element method for the nonstationary conduction convection problems,where the coupled equations governing viscous incompressible flow and heat transfer process,and incompressible fluid are the Boussinesq approximations to the nonstationary Navier Stokes equations.And have discussed the existence of semi discrete and fully discrete solutions,and derived the error estimates for the approximate solutions on the continuous and discrete time cases. |
