“…A modified wall function approach was employed to provide wall boundary layer solutions that are less sensitive to the near-wall grid spacing. Consequently, the model has combined the advantages of both the integrated-to-the-wall approach and the conventional law-of-the-wall approach by incorporating a complete velocity profile and a universal temperature profile [10].…”

The objectives of this study are to conduct a unified computational analysis for computing the design parameters such as axial thrust, convective and radiative wall heat fluxes for liquid rocket engine nozzles, so as to develop a computational strategy for computing those design parameters through parametric investigations. The computational methodology is based on a multidimensional, frOte-volume, turbulent, chemically reacting, radiating, unstructured-grid, and pressure-based formulation, with grid refinement capabilities. Systematic parametric studies on effects of wail boundary conditions, combustion chemistry, radiation coupling, computational cell shape, and grid refinement were performed and assessed. = heat capacity = diffusivity = total enthalpy = static enthalpy = radiative intensity = thermal conductivity = turbulent kinetic energy = nondimensional pressure = nondimensional heat flux = recovery factor = location coordinate = nondimensional temperature = law-of-the-wall temperature = time, s = mean velocities in three directions = wall friction velocity = nondimensional Cartesian coordinates = turbulent kinetic energy dissipation rate = energy dissipation contribution = absorption coefficient = viscosity = turbulent eddy viscosity (=pC,k%) = turbulent kinetic energy production = density = turbulence modeling constants = shear stress = direction vector. !2-denotes the leaving radiative intensity direction = chemical species production rate

“…The plug nozzle is made of a primary internal expansion nozzle, which is a conventional supersonic nozzle, and an external-expansion ramp, referred to as the plug surface. Most of the different engineering solutions proposed for plug nozzles have the following common feature: the primary expansion is made through a cluster of bell nozzles (or modules) exhausting onto a common linear plug surface [7][8][9].…”
