The implementation of oxy-fuel technology in fossil-fuel power generation could result in a drastic increase of system efficiencies and a reduction of emissions. While typical system temperatures are dictated by material constraints, open-cycle magnetohydrodynamic (MHD) power generators have the potential to utilize the energy of undiluted flames. This work presents design and modeling strategies to develop steady-state supersonic MHD combustors operating at temperatures exceeding 3000 K. Throughout the study, computational fluid dynamics (CFD) models were extensively used as a design and optimization tool. A proof-of-concept 60 kWth model was designed, manufactured and tested in accordance to methods relevant to rocket …

The Center for Space Exploration and Technology Research at the University of Texas at El Paso, has designed, built, and optimized an experimental high heat flux test facility to investigate the heat transfer coefficient of liquid methane and other cryogenic propellants for regenerative cooled rocket engine design. The system is composed of a copper conduction based thermal concentrator that delivers heat flow into a single sub-scaled cooling channel (test article). This study focuses on optimizing this design of the high heat flux test facility to develop a more accurate method for measuring the conductive heat flow going into the cooling …
