摘要:
在扩散控制蒸发模型的基础上,运用质量守恒、能量守恒和传热传质等基本定律,建立喷雾闪蒸的数学模型,使用MATLAB/Simulink进行求解,经计算得出闪蒸过程中液滴温度、直径、质量、蒸发速率和蒸发率的变化规律,使用控制变量法,研究了液滴初始温度、闪蒸环境压力、液滴直径对液滴的温度、直径、质量、蒸发速率和蒸发率随着时间的影响,得出了相应的结论。
Abstract:
Based on the diffusion control evaporation model, the basic laws of mass conservation, energy conservation and heat and mass transfer are used to establish a mathematical model of spray flashing.The solution is solved by MATLAB/Simulink,and the liquid in the flashing process is calculated.The influence of initial temperature,evaporation pressure and droplet diameter on the droplet’s temperature evolution,evaporation rate,flash efficiency and flash duration time was investigated and representative conclusion were made.
