Abstract:
1. A non-transitory machine-readable storage medium or non-transitory machine-readable media comprising one or more sequences of instructions which, when executed by one or more processors, simulates fluid flow in a simulation space by causing steps to be performed, comprising: [a] initializing a mesh comprising a plurality of cells, wherein each cell has associated geometric information related to the mesh and filtered field variables values; [b] inputting at least some of the values from the filtered field variables values and at least some of the geometric information of the cells in the mesh into a model to obtain correlation values for correlation terms in a set of large eddy simulation (LES) equations, the model obtaining the correlation values for a correlation term as a scaled difference between original field variables values associated with the correlation term and filtered field variables values associated with the correlation term, the difference being scaled by a scale factor that depends upon a number of dimensions of the mesh but that does not depend upon an empirical factor; and [c] using at least some of the filtered field variables values and at least some of the correlation values to solve the set of large eddy simulation (LES) equations to obtain updated filtered field variables values; wherein the scale factor is both time and space scaled; and wherein the scale factor is where α is dependent upon the number of dimension of the mesh.
