“…The methodology adopted to simulate the behaviour of the cooling jacket was accomplished through comparisons with the experimental results, obtained by means of an experimental breadboard (MTP-BB [54]), shown in Figure 9. This kind of breadboard was specifically conceived to collect experimental data on the transcritical behaviour inside a typical LRE-like channel configuration.…”

“…In fact, a narrow axial rectangular channel on the top of the breadboard body was realized, having the dimensions which are comparable to those of the DEMO cooling channels, as shown by Figure 9c, which shows the inlet flange/channel interface. Further information is available in [54]. The copper alloy body accommodates ten electrical cartridges, having a maximum power of about 12 kW, located in specific slots, to ensure that the desired heat flux was representative of that typically experienced in LRE cooling systems for the chosen operating conditions.…”

The cooling jackets of liquid rocket engines are composed of narrow passages surrounding the thrust chambers and ensure the reliable operation of the engine. Critical conditions may also be encountered, since the cooling jackets of cryogenic engines, such as those using LOX/LCH4 propellants, are based on a regenerative strategy, where the fuel is used as a refrigerant. Consequently, deterioration modes near where pseudocritical conditions are reached or low heat transfer coefficients where the fuel becomes a vapour and must therefore be managed. The verification of the cooling jacket behaviour to consolidate the design solutions in all the extreme points of the operating box represents a very important phase. The present paper discusses the full characterization of the HYPROB (HYdrocarbon PROpulsion test Bench Program) first unit of the final demonstrator, (DEMO-0A), by considering the working points within the limits of the operating box and comparisons with the nominal conditions are given. In this way, a full understanding of the cooling system behaviour, affecting the working of the entire thrust chamber, is accomplished. Moreover, the design strategy and choices have been confirmed, since the verifications also include potentially even more extreme conditions with respect to the nominal ones. The investigation has been numerically performed and supported the thermo-structural analyses accomplished before the final firing campaign, completed in December 2022. Since little information is available in the literature on LOX/LCH4 engines, suggestions are given as to the organization of the numerical simulations, which support the design of such rocket engine cooling systems.

“…This will eventually help us in designing effective design guidelines for supercritical boilers. Even inspiration from this can be drawn to explore other SF like methane which also experiences phenomena 28 similar to HTD at supercritical pressure when used as a coolant in rocket engines.…”
