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 1):
A computer implemented method for modeling transport processes in fluids comprising:\n approximating 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; treating each point of the plurality of points in space occupied by the model gas as a point of collisions for each of a plurality of ballistic particles having the ballistic trajectory in a same ending point at a same time; treating each of the plurality of points of original collisions as a point source; treating each of the plurality of points of ending collisions as a point sink; treating each of the plurality of ballistic particles moving from the point source to the point sink as a property carrier created in the point source at time of original collision by obtaining one or more of properties comprising one or more of mass, momentum, and energy of specific values being intrinsic to the point source, and ended in the point sink at time of ending collision by transferring one or more of properties of specific values in the point sink; 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 non-moving points at a given time, thereby formulating a system of integral property balance equations representing model gas flow in each of the plurality of non-moving points, wherein the plurality of ballistic particles comprises a plurality of converging ballistic particles and a plurality of diverging ballistic particles, and wherein each of the plurality of non-moving points is treated as the point sink for each of the plurality of converging ballistic particles and as the point source for each of the plurality of diverging ballistic particles; and computing flow of the model gas by resolving the system of integral property balance equations in each of the plurality of non-moving points at the given time, thereby reliably predicting gas flow including rarefied gas flow.
