However, to me, these terms not only still have meaning. These words do drive how I look at simulation. You can dismiss the “digital twin” as a buzzword. But that won’t solve your problem. As with other engineering methods, the goal of using simulation as a digital twin is to ...
Reference: Modelling Smoke Flow Using Computational Fluid Dynamics by TN Kardos, Fire Engineering Research Report 96/4, December 1996: "The phenomenon arises from a sudden entry of fresh air via a gravity current, into a closed space in which a fire has been burning. This space has accumulated...

engineering research you have to realize that you need make what you've learned available to the engineering community that needs to know it. If you have a lot of great stuff in your thesis it does the guy who design sewage pump no good because he can't get your thesis (he's never ...
1. With respect to the momentum equation, you need the uncorrected eddy viscosity (un-corrected meaning no effect of Richardson number). 2. With respect to the gamma-equation, you need the corrected eddy viscosity. So why is it you want to change the turbulence model and not simply modi...
Note that in all cases, particles larger than 45 μm are fully separated while the grade efficiencies of particles finer than 45 μm are dependent on the restitution coefficient meaning that up to this particle size agglomeration is playing a role in the performance of the studied cyclone. ...
II摘要高大空间建筑由于自身的特点,其气流组织是空调系统设计的难点,对于像体育馆这样的高大空间,比赛厅的温度、湿度、速度等参数是至关重要的,合理的室内参数不仅能够使运动员和观众感到舒服,更重要的是这些参数对所进行的比赛有重要的影响。像羽毛球、乒乓球这类的小球如果风速过大,超过规定的风速,则小球将会在空...
As expected, the layout efficiency decreased as turbines were added to the domain, meaning that wake losses are introduced in this process. For the simpler domains, we observed that this efficiency decrease was approximately linear with respect to the number of turbines. Complex phenomena were ...
(2)I find it very difficult to have an impact on designs by using CFD. Often my analysis is sort of after the fact, and just provides a pretty picture. Often the fast turn around time required on some analyses leaves me very uncomfortable as to the meaning and accuracy of the results....
