Based on the Matlab Simulation of the Maxwell Distribution

Abstract

Using MATLAB，the digital teaching software of Maxwell ’s speed distribution function is compiled. The software can deal with Maxwell speed distribution function in digital. This paper concerns mainly about the simulation of the speed distribution graph of the Maxwell speed distribution law and the speed distribution graph in different temperatures by using MATLAB Moreover, the three statistics is programmed and calculated

“…Consequently, the decrease in free volume due to elevated pressure could reduce the diffusion coefficient of fluid molecules. Moreover, the Maxwell curve of speed distribution shows the negative system pressure dependence of the average free path between molecules . The molecular free path decreases with elevated pressure, thereby weakening the diffusion capability of fluids .…”

“…Moreover, the Maxwell curve of speed distribution shows the negative system pressure dependence of the average free path between molecules. 72 The molecular free path decreases with elevated pressure, thereby weakening the diffusion capability of fluids. 73 In the latter point, elevated pressure leads to an increase in the number of molecules per unit volume.…”
