Neutral Particle Continuous Medium Module (NMEM)

It is possible to calculate flow considering compressibility and viscosity! The spatial distribution of density and flow rate can be determined for each type of gas component.

The "Neutral Particle Continuum Module (NMEM)" calculates the flow field of a mixed gas composed of multiple types of atoms and molecules (particles without charge). By solving the fundamental equations of fluid dynamics that take into account the diffusion of each neutral particle component, the flow rate and density of each component are calculated. These fundamental equations are applicable when the gas is considered as a continuum, specifically for Kn (Knudsen number; a dimensionless number that evaluates the rarity of the flow, defined as Kn = mean free path / representative length of the flow) approximately less than Kn < 0.01. 【Features】 ■ The spatial distribution of density and flow rate (flux) is obtained for each type of gas component. ■ Calculations of flow considering compressibility and viscosity can be performed. ■ Coupled calculations with plasma are possible (coupling with PHM or PIC-MCCM). *For more details, please refer to the PDF document or feel free to contact us.
