70 W Yb:YLF Cryogenically-Cooled Regenerative Amplifier

OSA High-brightness Sources and Light-driven Interactions Congress 2020 (EUVXRAY, HILAS, MICS), 2020
We demonstrate a cryogenically-cooled Yb:YLF regenerative amplifier delivering 20-mJ pulses at 3.5 kHz corresponding to 70 W average power. The pulses possess 2.1 nm spectral bandwidth centered at 1019 nm supporting sub-ps pulses.

Effect of film cooling/regenerative cooling on scramjet engine performances

Journal of Propulsion and Power, 1994
Film cooling was modeled to allow performance prediction of scramjet engine design. The model was based on experimental results of the compressible mixing layer for the vicinity of the injection slot, and on analytical results of the turbulent boundary layer in the region far from the slot.

Polybranched regenerative GAX cooling cycles

International Journal of Refrigeration, 1995
After 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.

Cryogenically cooled 30-mJ Yb:CaF2 Regenerative Amplifier

Lasers Congress 2016 (ASSL, LSC, LAC), 2016
We report on the design and performance of a cryogenic cw-pumped Yb:CaF2 CPA producing 30-mJ, 200-fs pulses. Operation in the repetition frequency range of 0.5—10 kHz is demonstrated, sustaining >15 W average power.

Life analysis of regenerative-cooling thrust chamber

2014 ISFMFE - 6th International Symposium on Fluid Machinery and Fluid Engineering, 2014
Thrust 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, 1971
A 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.
