Key words Laval nozzle, thrust-vectoring, shape and CFD Abstract:This study employed Computational Fluid Dynamics, CFD solution to configure the entire shape of the nozzle.
Then with a two-dimensional approach and coded FORTRAN programs, the convergent portion was handled with time matching CFD while the divergent portion was handled with space matching CFD.
However, in this study, we decided to consider the convergent and divergent portions separately and then merge the portions: while the convergent section is dealt with using time matching CFD, the divergent portion is handled with space matching CFD.
This post processing technique demonstrates that its absence often leads to highly non-optimal simulation strategies and errors in the simulation are found (if detected at all) after a Ssimulation has been run completely.
