最优化方法在确定对流混合层顶夹卷率中的应用 - The numerical isothermal solutions were obtained and the results were discussed. It was found that the directions of the combined entrainment velocity varied with varying directions of the two surface velocities, while the slanting angle of the contact ellipse within the calculation field also varied therewith.
结果表明：随着两表面速度方向的改变，合卷吸速度的方向不断变化，接触椭圆在计算域内的倾斜角度也随之改变； - An integral model of buoyant jets is given in this paper. The profiles for velocity density and concentration difference are assumed to be Gaussian distribution, and the relations of the entrainment rate with local densimetric Froude number and cross velocity are derived for closing the governing equations.
给出了基于积分方法的一种倾斜浮力射流的数学模型，且流速、密度和浓度差剖面假定为高斯分布，并导出了用来封闭该数学模型的较为完全的掺入率公式。 - The model also shows that the entrainment velocity, in addition to depending on the shear velocity and the ambient turbulent intensity, is also the function of the effective plume radius.
模式还显示，卷挟速度除取决于切变速度及湍流强度以外，还是烟流半径的函数，因而在物理上更加合理。 - The regularity of longitudinal distribution of entrainment rate which varied with observed Velocity, freeboard height, internals type, size and location, was studied respectively in the case of setting internals in dilute phase zone and condense phase zone.
研究了当内部构件分别设在稀相区和浓相区时，夹带速率的轴向分布随表观气速、自由空域内的高度及内部构件的类型、尺寸、放置位置的变化规律。 - With the increasing of Froude number, vorticity, air entrainment by plume and frequency descends, flame is longer and deviates from axis gradually. Besides axial velocity of plume also decreases for buoyancy attenuation.
分析发现，随着Fr数的增大，涡量减小，羽流卷吸空气的能力减弱，涡旋变化频率降低，火焰面增长并逐渐偏离对称轴，而且由于浮力减弱，羽流轴向速度呈下降趋势。
