Polybranched regenerative GAX cooling cycles
International Journal of Refrigeration, 1995After a short characterization of today's advanced absorption cooling systems, of multi-effect and generator-absorber heat exchange (GAX) type, this work introduces polybranched regenerative GAX cycles (PBR(GAX)). They combine the advantages of four cycles: GAX, branched GAX, regenerative GAX, and those with rectification heat recovery.

Life analysis of regenerative-cooling thrust chamber
2014 ISFMFE - 6th International Symposium on Fluid Machinery and Fluid Engineering, 2014Thrust chamber is an important part of liquid rocket engine (LRE), which always uses the structure of regenerative-cooling channels in order to lower the temperature of the wall. With the concept of reusability of LRE is advanced, the life analysis of regenerative-cooling chamber should be carried out.

Fixed-Bed Reactors with Regenerative Cooling
Industrial & Engineering Chemistry Fundamentals, 1971A regeneratively cooled fixed-bed reactor system was studied theoretically. It consists of two sections which alternate roles as reactor and heat regenerator by periodic flow reversals. Calculations were performed for a single exothermic reaction using a forward cell model.

Testing of regeneratively cooled light-weight panel
31st Joint Propulsion Conference and Exhibit, 1995Two types of actively cooled light-weight panels for use in scramjet engines were fabricated. They were made of Hastelloy X, and the photo-etching method was applied for constructing many cooling passages in these panels. One type of panels had a honeycomb structure which was brazed at the back of the panel for reinforcement.

Regenerative cooling for liquid rocket engines
Journal of Thermal Science, 1995Heat transfer in the thrust chamber is of great importance in the design of liquid propellant rocket engines. Regenerative cooling is an advanced method which can ensure not only the proper running but also higher performance of a rocket engine. The theoretical model is complicated, it relates to fluid dynamics, heat transfer, combustion, etc...

Performance evaluation of regenerative cooling/film cooling for hydrocarbon fueled scramjet engine
Acta Astronautica, 2018Abstract Thermal protection is considered to be a significant challenge for scramjet engine. In this paper, a combined cooling method which combines film cooling (F.C.) with regenerative cooling (R.C.) instead of single regenerative cooling for hydrocarbon fueled scramjet engine by using gaseous hydrocarbon fuel coming out of the cooling channel exit

Automation of regenerative compressor cooling system using microcontroller
2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015], 2015Since there is a need for enhanced efficiency system in power generation, regenerative compressor cooling has become a savior for the existing limited resources. The compressed air, commonly called industry's fourth utility, that is condensed and contained at a pressure greater than the atmosphere.
