Parametric Numerical Study on the Performance Characteristics of a Micro-Wave Rotor Gas Turbine

In this paper, an alternative micro-gas turbine is proposed, where the traditional compressor-turbine arrangement replaced by axial, throughflow wave rotor. The investigated rotor features symmetrically cambered wall profiles and angled port for shaft power extraction uses shock rarefaction waves pressure exchange to achieve gas compression expansion within a single device. A validated quasi-one-dimensional model that solves laminar Navier-Stokes equations using two-step Richtmyer scheme with minmod flux limiter employed characterise examine microgas behaviour. accounts heat transfer, flow leakage, friction inviscid blade forces. addition, modified boundary conditions consider finite passage opening effects simple steady-flow combustor defined links high in- outlet ports. used conduct parametric study investigate of leakage gap, release rate, exhaust backpressure, as well profile camber on performance focus generated efficiency, system efficiency. implications loss potential recuperator are discussed well. results identify axial primary drivers enhanced performance. Finally, reinforce capacity rotors compress expand efficiently, while thermal efficiency remains below 10 percent.
