Impact of nonequilibrium particle temperature considerations on seeded coal combustion plasma properties. Third and fourth quarterly reports, April 1, 1991--September 30, 1991
Description: The main purpose of this research is to investigate the impact of nonequilibrium temperatures of the post-combustion entrained particles on the generator-bound combustion plasma properties and consequently on the overall performance of the MHD channels for both Linear and Disk configurations in the typical coal-fired MHD environment. Aiming at this purpose are three major tasks. The first task is to establish a simulation model to present the steady state, non-equilibrium interactions between the post-combustion entrained particles and their carrier gases. The second task is to predict the overall performance of the MHD channels for both Linear and Disk configurations with the available fully-developed non-equilibrium simulation model. The third task is to evaluate the relative impact of gas-particle temperature difference on generator slag phenomena as well as MHD overall performance. This past quarter, the linear MHD channel simulation model has been completely specified and partially modified to incorporate considerations for nonequilibrium particle temperatures. Testing of the modified model with the initial values from the first submodel (Richter`s combustion zone model) and evaluation of the non-equilibrium particle temperature effect on the overall MHD performance is currently ongoing.
