摘要:
AbstractA finite element model is developed based on the penalty formulation to study incompressible laminar flows. The study includes a number of new quadrilateral and triangular elements for 2‐dimensional flows and a number of new hexahedral and tetrahedral elements for 3‐dimensional flows. All elements employ continuous velocity approximations and discontinuous pressure approximations respecting the LBB condition of numerical instability. An incremental Newton–Raphson method coupled with the Broyden method is used to solve the non‐linear equations. Several numerical examples (colliding flow, cavity flow, etc.) are presented to assess the efficiency of e

摘要:
AbstractThe Asymptotic Finite Element method for improvement of standard finite element solutions of perturbation equations by the addition of asymptotic corrections to the right hand side terms is presented. It is applied here to 1‐D and 2‐D diffusion–convection equations and to non‐linear similarity equations. Excellent results were obtained without the a priori use of special trial and test functions. Theoretical expectations were co

摘要:
AbstractAn improved Vorticity–Potential method is presented for the numerical solutions of three‐dimensional duct flow problems. The solution procedure requires first a potential solution. Then the viscous effects are added through the vorticity transport equation. By using body‐fitted coordinates, the method is applied to simulate the incompressible laminar flows in a square elbow and in a twisted square
