Case Study for the Prediction of Effect of Aspect Ratio Five on the Heat Transfer Characteristics of Regeneratively Cooled Thrust Chamber By Considering Subcooling
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 1
Abstract
In this paper, Computational Fluid Dynamics technique is used to investigate the rocket thrust chamber cooling characteristics. The scope of the investigation involves the study of effect of aspect ratio (height/width) and sub cooling on the heat transfer characteristics of coolant channel. Steady state pressure based analysis is carried out in work. The temperature distributions of coolant along the coolant channel, temperature distributions of copper and stainless steel walls are the main focus of the study. The effect of film cooling and sub cooling are also studied in the analysis.In all above mentioned cases the, the coolant(kerosene ,which is the fuel) enters at the aft end of the thrust chamber and passes through the rectangular cooling channels before it is fed to the injectors.
