To figure out the law of the height of stirred blade installed inside the reactor affect the fluid inside, this article used CFD to Numerical simulation of the liquid filled area of the stirred reactor, then obtain the distribution of the liquid velocity field inside the reactor.Through the comparison of calculation. Consider the weak area of stirred mainly concentrated above the stirred blade, when stirred blade were installed at the stirred blade mounting height-to-liquid level-ratio reach to 40%, ti means the mixing level reach maximum, according to the calculation the average turbulence kinetic energy is 0.003407-40 0.002994-45. and standard deviation of turbulence kinetic energy is able to stable between 0.001503-40 to 0.001275-45.
