the rotating detonation wave Engine Concept a brief status report
49th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2011Co-Authors: K KailasanathAbstract:rotating detonation-wave Engine. The flow field within the Engine is shown to be fairly complicated. However, it follows the "steady-state" thermal detonation cycle quite closely, unlike the PDE. Parametric studies varying the pressure conditions both upstream at the inlet plane and downstream through the back pressure reveal that the overall specific impulse is just a function of the ratio of the inlet stagnation pressure to the chamber back pressure for the generic device considered here. Sources of losses occur when the reactant is burned away from the detonation wave, and also when detonated reactants are forced through both the oblique and secondary shock waves.

Use of Particle Heat Carriers in the Stirling Engine Concept
Energy Technology, 2016Co-Authors: Huili Zhang, Tim Gowing, Jan Degrève, T. Leadbeater, Jan BaeyensAbstract:The Stirling Engine has drawn new attention for its high efficiency and flexibility towards the application of different heat sources. A new Stirling Engine application in a renewable energy combined heat and power (CHP) Concept will be presented, in which powders are used as the heat carrier between the hot storage and the ultimate Stirling reuse. A fluidized bed of small particles (50–150 μm) is examined in this study. The outside heat transfer coefficient to the finned Stirling heat exchanger largely exceeds 1500 W m−2 K−1 at very low fluidization velocities, which is, therefore, not the heat transfer limitation. Positron emission particle tracking experiments demonstrated that the particle movement and mixing in the fluidized bed are not hampered by the presence of the finned heat transfer tube. As the Stirling Engine can reach efficiencies in excess of 30 % and has the potential to be integrated in a CHP mode of operation, it should be considered as a hot research topic in the renewable energy sector.
