FACTORS THAT INFLUENCE THE OPERATION OF THE ROCKET SYSTEM
Compressibility is unavoidable in high-velocity gas flows, and it is accompanied by appreciable physical changes coupled with complex interaction with performance factors. When designing a high velocity flow system, it is necessary to recognize that compressibility produces a separate set of physical results which may involve significant variations in density, pressure and temperature. Interest in this study is therefore to identify the relevant features and where possible, how they interact with system performance. The equations of continuity, momentum, and energy may be required in the study of fluid flows. For compressible flows, a number of numerical models are available and these include the One-Equation Model (Spalart-Allmaras) and Two-Equation standard k–ε models in its various forms. The Spalart Allmaras model is considered a viable model option for the study of the characteristics of compressible high-velocity rocket system. Various forms of drag losses occur in supersonic fluid flow systems. For the re-entry vehicle a blunt nosed leading-edge design is adopted for temperature reduction in this region.
