基于蒙特卡罗方法的水扩散系数及其与温度的关系
The relationship between diffusion coefficient of water and temperature based on Monte Carlo method
摘要
Abstract
Based on Monte Carlo method,self-diffusion process of water molecules in water is simulated,and then self-diffusion coefficients of water are estimated.By calculating self-diffusion coefficients of water at one atmosphere and under different temperature conditions,and comparing the calculated values and the value in the literature under the same condition,it is found that their values are close to each other.This demonstrates that the simulation method is successful.Moreover,the relation between simulated self-diffusion coefficients and temperature is studied,the results reveal that diffusion coefficient increases rapidly as the temperature rise,and there is a negative exponential relation between diffusion coefficient and the reciprocal of temperature.This is in good agreement with the experimental and theoretical results.关键词
