Numerical Simulation Investigation on MHD Power Generation Channel of Energy Bypass Combined Engine
摘要
Abstract
With simplified one - dimensional low magnetic Reynolds number MHD equations, this paper involves study on the numerical simulation of ideal Faraday MHD power generation channel, analyzing influence that the change of electromagnetic parameters and channel geometry parameters have on the performance of MHD power generation channel. Results show that MHD power generation channel can reduce flow velocity and total temperature, and extract energy effectively. However, it can inflict losses upon total pressure because of electromagnetic irreversible and Joule heat effects. Increasing of magnetic field strength and electric conductivity means role in enhancing of electromagnetic. A reasonable expand channel can efficiently refrain from static temperature, flow velocity and total temperature at the exit, and get the favorable influencing factors of electromagnetic. Effect of decreasing in outlet velocity, total temperature as well as total pressure and increasing in extracting - energy - rate can be received by enhancing parameters such as magnetic field strength, electric conductivity. Otherwise, magnetic field strength and electric conductivity should be diminished.关键词
