Each MOLE costs RMB 280,000. Maybe the expensive provides good Continue reading Caution! Pseudo-Science to Anti-Terrorist
Zhang Zhihong, one of the students in our laboratory, also one of the best friends in the lab, has finished his master degree thesis defense in this afternoon. His study was on the flow simulation in the condensing heat exchanger Continue reading Have a nice Future, Zhang Zhihong
OpenCFD has announced a new version of OpenFOAM, version 1.5 on July 14, 2008. The new version has some major changes, such as a lot of new and demonstration applications with examples, a new mesh utility including cell layer insertion, Continue reading OpenFOAM 1.5 Released
Swimming is a kind of sports. CFD (Computational Fluid Dynamics) is to analyze fluid flow numerically using computers with some discrete models. Because of movement in water, the resistance generates. In order to decrease the resistance to improve the movement Continue reading Swimming and CFD
Today afternoon, I went swimming, which was my first swimming this year. I have swimmed for about 500 meters with breaststroke, which is the only swimming style I can do. I learned to swim at the university. Before that, I Continue reading First Swimming This Year
Generally, in the explicit schemes of differential method, Courant number is an important number which should be less than 1 in order to assure the stability. However, if the Courant number is too small, much computation time will be lost. Continue reading Run a Case with Variable Time Step in OpenFOAM
