Cooling Performance Analysis of Regeneratively Cooled Combustion Chamber
Journal of the Korean Society for Aeronautical & Space Sciences, 2004 A regenerative cooling system has been designed through empirical 1-D analysis for a liquid rocket engine of 30-ton-level thrust. The hot-gas-side wall temperature from 1-D analysis shows 100K difference compared to 3D CFD analysis. Two variations of design with same cooling performance are suggested for different maximum channel widths i.e., 4mm and ...
