“…Rocket engines based on an expander cycle have been of continued interest for industries and space agencies, as demonstrated by the development of RL-10 in all its configurations in the U.S. since the 1960s [2,3], of RD0146 in Russia [4], of LE-5B in Japan [5], and of Vinci in Europe [6]. The choice of propellants (oxidizer and fuel) to be used in such engines is not arbitrary, and in fact, all of the mentioned expander cycle engines are operated with hydrogen=oxygen propellant combination.…”

Heat transfer enhancement due to longitudinal wall ribs inserted in a rocket engine thrust chamber is analyzed by means of a Reynolds-Averaged Navier-Stokes equations solver. A ribbed wall experiment is numerically reproduced to assess the capability of the simplified approach to properly capture the heat transfer enhancement. Then, a parametric analysis on the role of the longitudinal rib height on heat transfer enhancement is made on a sample thrust chamber. Results show the expected heat increase related to the surface increase, and highlight the reduction of efficiency for increasing rib height due to the thermal stratification between ribs.
