| Abstract: | The transonic flow field around NACA 0012 airfoil is calculated by finite element method from pressure minimum integration,full potential equation being used.The artificial viscosity is introduced by way of using artificial density.The computational mesh,is generated automatically in terms of analytical/numerical transformation.SLOR and pseudo-time iterative method are employed for solving finite element equation.Several numerical solutions are given. |
