Abstract
Received 01.02.2020, received in revised form 13.03.2020, accepted 20.05.2020 Abstract. Due to the kinetic approach the modelling description of the drop evaporation is offer. The main equation of the theory received due to the conservation law of dissipative functions of the vapor – liquid system. The diapason of drop size it’s finding when its stability. It’s comparison of the results with the famous classical is given. The numerical estimate of the linear size of small disperse phase when take place usually evaporation (i.e. the Knudsen’s number is a small Kn = l R ≪ 1, where l is a free length path of the molecule and R is an drop radius) are given.
收稿日期:01.02.2020,收稿日期:13.03.2020,收稿日期:20.05.2020利用动力学方法对液滴蒸发过程进行了建模描述。由于汽液系统耗散函数的守恒定律,该理论的主要方程得到了认可。当它稳定时,它找到了液滴大小的变化规律。并与著名的经典作了比较。给出了通常发生蒸发时的小分散相的线性尺寸的数值估计(即Knudsen数Kn = l R≪1,其中l是分子的自由长度路径,R是水滴半径)。
