... Averaged Navier-Stokes equations Solver(RANS), k-ε turbulence model and Discrete Phase Model(DPM) in the ANSYS Fluent code. Using the developed coal-gas flow analysis model, computations are carried out to investigate the gas flow path, the coal particle behavior and the pressure loss characteristics...

... flow rate, we consider that the pressure of turbine inlet does not easily get higher by the pressure loss of vapor-liquid separator under the condition of increasing the warm source. From the above, both hT and mTH increase when the flow rate of heat source is increased, turbine power gets bigger...
