ABSTRACT
It is not only a dream but also a necessity of tomorrow to have vertical and short takeoffs and landings in the civil aviation sector; because of rapid growth of aviation for humanitarian purposes. The main geometric parameters such as the ratio of the nozzle throat diameter to the exit curvature radius have been considered for the present study. The optimum number of grid has been determined through the numerical computation of the grid at different refinement levels of the grid at the curved surface. Before going into the details of the computational study, it is customary to define the road map of the design parameters. The flow behaviors have been studied in detail. The flow and geometric parameters for the design of such a nozzle have been recognized through the computational fluid dynamics analysis. The correlation will be developed after the experimental database for calculation of thrust and deflection angle.
