Professor David Schmidt of the Mechanical and Industrial Engineering Department was the keynote speaker at the Open Source CFD (Computational Fluid Dynamics) International 2010 conference, held in Munich, Germany, on November 4 and 5. The title of his talk was “Multi-scale Challenges in Multiphase CFD [Computational Fluid Dynamics].” As Dr. Schmidt explains, “The talk compared three methods used in my research group for simulating multiphase flow. At high speeds, these multiphase flows have features that range from tiny droplets, only a few microns in size, up to device-scale features that may extend several centimeters.”
Computational fluid dynamics is a branch of fluid mechanics using numerical methods and algorithms to solve and analyze problems that involve fluid flows. In computational fluid dynamics, computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions.
“The engineering community typically uses computational methods that are fast but inaccurate, or they may employ computationally expensive methods that are more precise,” Schmidt notes. “The talk largely emphasized new techniques for staking out a middle ground, achieving good fidelity, and requiring only desktop computer resources.”
This year's Open Source CFD conference built upon the considerable interest and success of those who are using, programming, and deploying open source CFD solutions. The Conference in Munich was aimed at: existing open source CFD software, e.g. OpenFOAM® users; CFD engineers seeking to investigate open source technology; industry managers and IT implementers; academia; and technology consultants.
