A two-fluid Euler-Euler model of two-phase turbulence

for describing the gas and liquid-phase turbulence respectively

has been established

and the flow behavior of gas-liquid two-phase flow in the process of gas penetrating liquid pool in scrubo-cooling chamber of the new type coal-water slurry gasifier being simulated.Through comparison with the test results

it shows that the said model can better predict the gas-liquid flow behavior in scrubo-cooling chamber of the gasifier.It is found from study that the gas in flow process of turning upward aggragates along the outer wall of cooling pipe and rises mainly along the periphery of cooling pipe

and the rising velocity is larger

the turbulent kinetic energy of gas and liquid occurred mainly near the exit and outer wall of said cooling
