Computational dynamics of fluid controlled mechanical thrust-vectoring nozzle

Abstract

Computational Fluid Dynamics (CFD) have been used to provide solutions to configure the shape of a nozzle, considered to be as short as possible, without shocks and separation; yet able to meet the desired propulsive and vectoring needs. The problems associated with geometrical shape using one-dimensional approach were high-lighted. With two-dimensional CFD approach coded with FORTRAN programs, the convergent portion was handled with time matching technique, while the divergent portion was handled with space matching technique. Analysis of post-processing data gave results in agreement with that obtained by analytical approach. The computational method demonstrated the significance and benefits of CFD algorithms and numerical experiment-ation to configure and enhance the nozzle profile by providing quick solutions.
