Ah, I see, quantum theory are not that far from our laymen.

comment Is there any solution to the potential flow around a square cylinder?
I am well aware of these simulations and papers. I run these simulations myself. These days, I am thinking of force history issue. As you refine the mesh or as you choose different turb models, the unsteady force turns out to be different, this bothers me. So I want to start from a potential flow results. I use a potential solver to get an initial field. But I found as the mesh is refined, the velocity at the corner cells keep increasing.

Okay, you are right. Do you know any viscous solution to the flow past a square cylinder, or any related paper? I am very interested in these type of sharp cornered external flow.

Thanks, I used those two tags just in hope that other "turbulence and navier-stokes" guys may see this post and share some ideas too. Cause I am afraid the fluid people is not too many here.

Any analytical results? Or references that I can look into? Thanks

Hey, I love your six fingers theory!

Excellent! These kind of information is exactly what I need. I hope there is some research on time zone issues too!

HAHA, I am just afraid that the people on Skeptics are not familiar with "energy" or "science" topic enough...

comment US time zones and Daylight saving time, energy efficient?
Thanks! Of cause, politics, economy, culture, and science are all equally important. I did know that some members of our gov believes that NOT using time zones would keep China chicken shaped. Which means Tibet and Xinjiang would not go away from us. LOL But I do hope to see if there is anyone in the US who has done a research from energy aspect to study this problem.
