【摘要】 利用线性不稳定性理论对加热条件下粘性液膜射流模型所对应的色散方程进行了数值求解。利用得到的计算结果研究了加热条件下无量纲数对液膜射流破碎尺度的影响。结果表明:在反对称模式下,当We·Q<1时,液膜破碎处于大尺度模式,反之则处于小尺度模式;在对称模式下,当We·Q<1且Ma<Macri时,液膜破碎处于大尺度模式,反之则处于小尺度模式。更多还原

【Abstract】 Using the calculation results of the dispersion equation of a moving liquid sheet with viscosity and temperature gradient, the effect of dimensionless numbers on the breakup scale of liquid sheets is studied.The results show that under sinuous mode,when We·Q<1,the breakup of liquid sheet is in Largescale regime,otherwise,it is in smallscale regime,and under varicose mode ,when We·Q<1 as Ma<Macri,it is in Largescale regime,otherwise,in smallscale regime.更多还原
