Design optimization of bell rocket nozzle; numerical studies using LESdoi:10.2514/6.2022-3806The effect of the overexpansion on the efficiency of bell nozzle is computationally studied using the large-eddy simulation (LES) approach. The studies are conducted for three different altitudes 0m, 5,000...

For ideal nozzles, basically two different types of shock structures in the plume may appear for overexpanded flow conditions, a regular shock reflection or a Mach reflection at the nozzle centreline. Especially for rocket propulsion, other nozzle types
The side-load character strongly depends on the nozzle design, and is a key feature for the nozzle's mechanical structure layout. It is shown especially for the VULCAIN and VULCAIN 2 nozzle, how specific shock patterns evolve during transients, and how - by the nozzle design - undesired flow...
With more than a third of the text and illustrations either completely new or extensively revised, this latest edition includes current information on engine structures, nozzle theory, gas properties, thrust chambers, launch vehicles, and more. With a detailed table of contents breaking down each ch...
The internal nozzle flow development of a solid rocket plays an essential role both in nozzle design and performance. In particular, the mean velocity field, the axial pressure distribution and the turbulence characteristics have a strong and direct impact on many physical processes occurring within ...
The first step was to calculate the isotropic 1-D flow along the nozzle using the Finite Difference Method, reaching estimative values of pressure and velocity. Then, a new study was carried out using Computational Fluid Dynamics (CFD), particularly the finite volume method, in a 2-D mesh ...
