非牛顿流体在气液搅拌槽内强制流动传热特征研究

NON-NEWTONIAN FLUID FLOW AND HEAT TRANSFER IN MECHANICALLY AGITATED GAS-LIQUID VESSELLS

为了确定非牛顿流体气液搅拌流动传热特征，对气体有效分散区域（载点）提出了无因次准数关联式，并就两种不同叶轮搅拌的通气管外传热系数作了比较．关键词##4气液搅拌;;载点;;

For characterizing non-newtonian fluid flow and heat transfer in mechanically agitated gasliquid vessells, the dimensionless group relationships are proposed on completely gas dispersed area (loading point ). and comparisions butween outside film coefficients for coil in two vessells with differrent turbine impellers are made.
