This paper develops a robust and practical design for supersonic nozzles to be used in an altitude engine test facility.

The flow-fields and thrust of the aerospike nozzle, for the full and truncated nozzles, were investigated.

The purpose of this study is to investigate other rocket nozzles that might have the ability to improve performance of a propulsion system without a large penalty on vehicle mass or cost.

Preliminary design optimal techniques were adopted to reduce nozzle length while keeping the exit area constant in the design.

Optimization produced a smooth flow by generating a parallel and uniform flow at the exit. in Aeronautical Engineering from Seoul National University in 19, respectively. D from the University of Illinois in Urbana-Champaign in 1992. Lee is currently a Professor at the Department of Aerospace Engineering in Konkuk University in Seoul, Korea.This results in drastic changes in the fluid properties, which makes cooling analysis a challenge. Combustion instabilities hindered early development. The final design iteration achieved a C* efficiency of greater than 90% in a form factor small enough to fit in...This thesis describes a two-pronged approach to tackle this problem. In this MSc thesis, a 4N Bi-Propellant rocket motor was designed using numerical analysis tools. Hypresearch is a project that has been under development with the collaboration of ATG Europe, TU Delft, TNO for the past 7 years.The optimal design produced a uniform and parallel flow at the given test condition. Her research interests are in the area of computational fluid dynamics of nozzle flow and LES analysis of flow instabilities in hybrid rocket. "The cold-gas propulsion system being developed by M-SAT requires improvements to its original nozzle design.This study documents the research, design, and analysis of a supersonic plug nozzle concept that could be integrated to the refrigerant-based cold-gas propulsion system to possibly improve its performance.As documented in this thesis, CFD analysis showed that the outlined nozzle design method resulted in a feasible nozzle concept that has the ability to out-perform a conventional nozzle of the same area ratio.Three spray characteristics were chosen as a measure of Atomization quality: the Sauter Mean Diameter (SMD), the drop size distribution, and the cone angle....The influence of using different chemistry model and different chemical kinetics schemes on modeling combustion inside a rocket engine igniter are investigated.By continuing to use this site, you consent to the use of cookies.We use cookies to offer you a better experience, personalize content, tailor advertising, provide social media features, and better understand the use of our services.
