Abstract:
An improved computer implemented method for modeling transport processes in fluids is disclosed. Instead of modeling based on using an infinitesimal fluid element of a continuous medium, the method approximates fluid flow in a fluid system as a model gas flow in a model gas system being identical to the fluid system. The method is adapted to model gas flow including dilute gas flow for high Knudsen numbers (Kn). The method delivers a new basis for prediction of dynamic evolution of the model gas system by considering a pre-established or known dynamic history of the system during a pre-initial period. A new generation of Computational Fluid Dynamics software products, which are based on the disclosed analytical tools and methods, are anticipated having capability to modeling gases from the continuum flow regime (Kn<0.01) to the free molecular flow regime (Kn>10), considerably higher accuracy of prediction, and lower computation cost.
