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 33):
A system for computational fluid dynamics analysis comprising:\n means for specifying geometry model of a fluid system, which is approximated to a model gas system, including configurations, dimensions, materials, temperature, pressure, and a pre-initial time and an initial time; means for transferring into memory a set of discretization parameters, wherein the set of discretization parameters comprises a set of points including a set of points in space occupied by a model gas and a set of points on one or more of gas-solid interfaces being in contact with the model gas, the set of points in which the model gas system is identified by defining model gas material, pressure, temperature, external forces, and other properties comprising one or more of mass, momentum, and energy during a time period from the pre-initial time until the initial time; means for transferring into memory a set of positions of linked points connecting a non-moving point of the set of points in space to each of other points of the set of points; means for computing, for each of two points of the set of positions of linked points, a converging ballistic trajectory of a particle having a starting point in one of the set of points and targeting a non-moving point at a given time; means for computing for each of converging ballistic trajectories a starting time; means for computing a local initial time in each of the set of points; means for specifying property value obtained by each of converging ballistic particles at the starting time, wherein, when the starting time is less than the local initial time, then property value is defined by a pre-established property value; means for computing a probability of traveling along the converging ballistic trajectory; means for computing a net rate of property influx per unit volume in each of a set of non-moving points at the given time from the model gas system by calculating an impact of converging ballistic particles targeting the non-moving point at the given time; means for computing, for each of two points of the set of positions of linked points, a diverging ballistic trajectory of a particle escaping the non-moving point at the given time; means for identifying property value obtained by each of diverging ballistic particles at the given time; means for computing probability of traveling along the diverging ballistic trajectory; means for computing a net rate of property efflux per unit volume from each of the set of non-moving points at the given time; means for formulating an integral property balance equation by establishing a property balance at the given time between the net rate of property influx and the net rate of property efflux in each of the set of non-moving points; and means for solving the integral property balance equation and obtaining property value in each of the set of points in space at the given time, thereby reliably predicting gas flow including rarefied gas flow.
