Methane has many possible advantages as a fuel for reusable rocket engines and is therefore extensively discussed. However, the characteristics of methane as a coolant in a regenerative cooling system are widely unknown. Especially the heat transfer deterioration that occurs in the vicinity of the critical point is a major concern and a severe drawback. To investigate this phenomenon and to establish a broad data basis for the validation of numerical simulations, tests were performed with a subscale combustion chamber. The combustion chamber contains different cooling channel geometries (rectangular cooling channels with the aspect ratios [height-to-width ratio]: 1.7, 3.5, 9.2, and 30) and was cooled with cryogenic methane. Results close to the critical point show a distinct maximum in hot gas wall temperature, which is a clear evidence of heat transfer deterioration. The test results indicate a strong dependency on the occurrence of this effect toward cooling channels with a low aspect ratio.

“…Rocket is an aerospace vehicle that has strategic meaning. This vehicle can be used as a satellite launcher (RPS), weather research rockets, guided rockets, ground-to-ground, ground-to-air and airto-air ballistic rockets [1]. In other words, rockets can also function as equipment to maintain sovereignty.…”

“…Supercritical cryogenic combustion is often encountered in rocket engines. This has motivated modeling and numerical simulation of supercritical mixing and combustion in laminar flows [1,2,3,4,5,6,7,8,9] and turbulent flows [10,11,12,13,14,15,16,17] as well as model rocket combustor experiments [18,19,20,21]. At such high-pressure and low temperature conditions, however, multicomponent transport phenomena is highly complex and nonidealities may influence the structure and dynamics of mixing zones as well as flames.…”
