摘要: 提出热子动力学模拟方法,以理想气体中的热质粒子即热子为模拟对象,建立热子间的碰撞模型,统计可获得热子气系统的热力学性质,实现对热质的直接模拟.基于该方法,对氩热子气的平衡态系统和非平衡态系统进行模拟计算,模拟计算的热子气的状态方程同理论表达式一致,准确得到了氩气热导率在微纳尺度下的变化规律,验证了热子动力学模拟方法的可行性.

Abstract: We propose a simulation method, thermonar dynamics (TD) simulation. Thermons in ideal gases can be simulated directly by TD method. A collision model between thermons is established and thermodynamic properties of thermon gas are obtained. By TD simulation method, equilibrium and non-equilibrium thermon gas of argon are simulated. Simulated pressures of equilibrium systems agree with the equation of state of thermon gas predicted by thermomass theory. Simulated thermal conductivities are consistent with experimental and theoretical data. Feasibility of the proposed thermonar dynamics method is shown.

Key words: thermonar dynamics simulation, thermomass theory, thermon gas, non-Fourier heat conduction
