Patent number: 10831952Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing data representing the effect of tortuosity on the acoustic behavior of a fluid in a porous medium. One of the methods includes generating by a first data processing program of the data processing apparatus, a model of acoustic behavior of a fluid in a porous medium including an effect of tortuosity, with the model comprising a time variable indicative of a sound speed of the fluid. The method includes rescaling the time variable of the model based on the sound speed in a fluid in the porous medium. The method also includes simulating the acoustic behavior including the effect of tortuosity of the porous medium based on the rescaling of the time-related variables within the model.Type: GrantFiled: March 12, 2019Date of Patent: November 10, 2020Assignee: Dassault Systemes Simulia Corp.Inventors: Chenghai Sun, Franck Léon Pérot, Raoyang Zhang, Hudong Chen, David M. Freed, Ilya Staroselsky, Adrien Mann

Patent number: 9542506Abstract: A method for simulating a fluid flow that includes a laminar to turbulent boundary layer transition on a computer, the method comprising: for one or more locations on or near a boundary surface: performing a first calculation where a local boundary layer is taken to be a laminar boundary layer; performing a second calculation where the local boundary layer is taken to be a turbulent boundary layer; comparing a result from the first calculation to a result from the second calculation; and based on the comparing, selecting the result of the first calculation or the result of the second calculation; and inputting the selected result for the one or more locations into a simulation of activity of a fluid in a volume comprising the boundary surface.Type: GrantFiled: November 13, 2012Date of Patent: January 10, 2017Assignee: Exa CorporationInventors: Hudong Chen, Rupesh Kotapati, Raoyang Zhang, Richard Shock, Ilya Staroselsky, Yanbing Li

Patent number: 9223909Abstract: A fluid flow is simulated by causing a computer to perform operations on data stored in the memory to compute at least one eddy of a fluid flow at a first scale and perform operations to compute at least one eddy of the fluid flow at both the first scale and a second scale. The second scale is a finer scale than the first scale, and the computation of the at least one eddy of the fluid flow at the second scale is constrained by results of the computation of the at least one eddy of the fluid flow at the first scale.Type: GrantFiled: July 17, 2013Date of Patent: December 29, 2015Assignee: Exa CorporationInventors: Hudong Chen, Steven Orszag, Ilya Staroselsky, Victor Yakhot, Raoyang Zhang
