Elliptic Grid Generation And Its Application

Grid generation is one of the key problems in CFD and the numerical generation technique using partial differential equation is widely used and frequently studied, one of which elliptic equation in common use. The grid generation of complex-shaped aerocraft is researched using the concrete object of Dispenser. After redistributing its surface, three-dimensional body-fitted grid is generated by solving elliptic partial differential equations, namely elliptic grid generation. The program of computing N-S equation is used to get the desiring results of varieties of attack angles and velocities. It is concluded that the results accord with the aerodynamics rules, so the computing results will instruct the experiment to some degree.
