【摘要】 利用对具有温度梯度的粘性液膜射流模型进行的不稳定性计算结果,研究了实际射流参数(射流速度、气体密度、液体粘性、液膜厚度、温度梯度、液体种类等)对对称模式扰动作用下液膜射流大、小尺度破碎模式破碎特征的影响规律,并探讨了决定液膜射流破碎尺度的实际因素。更多还原

【Abstract】 Based on linear instability theory, by using the calculated results of moving liquid sheets with viscosity and temperature gradient, the effects of jet parameters, including sheet velocity, sheet thickness, gas density, liquid viscosity and temperature gradient, on the growth rate and dominant frequency of surface wave of liquid sheets under sinuous mode are studied in detail.更多还原
