Based on linear instability theory, the dispersion equation of a moving liquid sheet with viscosity and temperature gradient was solved by digital calculation.
利用线性不稳定性理论,对具有温度梯度的粘性液膜射流模型所对应的色散方程进行了数值求解。
The liquid sheet flow in the near region from swirl nozzle was analyzed theoretically.
从理论上分析了旋流喷嘴喷出的中空射流近区域的液膜的运动 ,在只考虑液膜表面张力的作用下 ,应用质量守恒和动量定理 ,建立了描述液膜运动的非线性常微分(积分 )方程组 ,该方程组可以用数值方法方便地求解 ,结果表示 ,液体离开旋流喷嘴后在自由空间形成的液膜呈葫芦形状 ,其速度和液膜厚度等都周期性地变化。
