Member since:June 13, 2006Total points:130 (Level 1)I am trying to go beyond the standard dentist visits that put the thin lead vests over your chest & torso to protect your vital organs. I want to take this process to the next level, so I was curious to know if there is an inexpensive material that can block radio waves and more common forms of radiation.Answer Question

Open Question: Why do you have to rub a material in one direction to charge a solid material?

Open Question: Why do you have to rub a material in one direction to charge a solid material?

I have never found this to be true. I rub a balloon backwards and forwards on what is left of my hair and the balloon charges.

I rub and ebony rod backwards and forwards with fur and it charges.

So I can't agree with the substance of the question.

Open Question: Where can I find CFD learning material ?

Open Question: Where can I find CFD learning material ?

I'm currently working on a research project in wind engineering, which involves CFD (Computational Fluid Dynamics) simulations. However, I have little knowledge of it. I am quite good at the basic application now but I want to study about it. Is there any good text book with brief coverage of theory and lots of application ? I want to do simulations with two different fluids, dynamic meshes and merged with FEM (finite element methods). I'm using ANSYS12.0 if that helps

Thank you !
