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.

Claim (Index 27):
A computer implemented method for modeling transport processes in fluids being in a stable condition comprising steps of:\n approximating a fluid flow in a fluid system as a flow of a model gas in a model gas system being identical to the fluid system; assuming that each of a plurality of particles, which compose the model gas, travels with a probability between any of two points of a plurality of points in space occupied by the model gas by following a ballistic trajectory governed by a law of motion, the ballistic trajectory having a starting point in one of a plurality of points of original collisions and an ending point in one of a plurality of points of ending collisions; assuming that each of a plurality of ballistic particles transports a combination of one or more of properties comprising one or more of mass, momentum, and energy between one of the plurality of points of original collisions and one of the plurality of points of ending collisions; specifying geometry and boundary conditions; defining a net rate of property influx per unit volume from the model gas system in a general point of a plurality of non-moving points in space occupied by the model gas, the net rate of property influx per unit volume, which is formed by way of a plurality of converging ballistic particles, each of the plurality of converging ballistic particles is selected from the plurality of ballistic particles by the ballistic trajectory having the ending point in the general point of the plurality of non-moving points in space occupied by the model pas; defining a net rate of property efflux per unit volume from the general point, the net rate of property efflux per unit volume, which is formed by way of a plurality of diverging ballistic particles, each of the plurality of diverging particles is selected from the plurality of ballistic particles by the ballistic trajectory having the starting point in the general point of the plurality of non-moving points; forming an integral property balance equation for each of one or more properties being transported by the plurality of ballistic particles in each of a plurality of general points, thereby formulating a system of integral property balance equations representing model gas flow in each of the plurality of general points, wherein the integral property balance equation is established in a way that, in the general point, the net rate of property influx per unit volume is equated the net rate of property efflux per unit volume; and computing the flow of the model gas, wherein computing the flow of the model gas comprises resolving a system of one or more of integral property balance equations in each of the plurality of general points, thereby reliably predicting gas flow including rarefied gas flow.
