Three weighted residual methods are used to analyse several linear and nonlinear model problems related to the stream function-vortidty formulation of the Navier-Stokes equations. These methods are then used to solve the driven cavity problem. 'The results obtained at Reynolds numbers of 100 and 400

This paper describes a boundary element scheme for solving steady-state convection-di usion problems at high PΓ eclet numbers. A special treatment of the singular integrals is included which uses discontinuous elements and a regularization procedure. Transformations are performed to avoid directly e
The use of orthogonal mapping procedures in heat-transfer analysis is often restricted to cases of isothermal and/or insulated boundaries. It is shown that a graphical construction called the "fictive isothermal surface" having certain welldefined properties will permit such mapping solutions to be
