I'm working on a simulation of water drops falling into a pool. I'm specifically interested in the waves generated by the impact of the drops. In order to calculate the vertical motion of the waves, I believe that I need to know the "stiffness" and damping constants of water.

I'm wondering if anyone can give me, or can point me to a book that has, those values? Would they be related to viscosity?

I'm no physics expert, so if this is something that doesn't make sense to ask, please let me know and I'll edit or delete the question. My thinking is that I can treat the drop, whose mass and velocity I know, as an impulse input to the water which (at the point of impact) can be treated like a "mass-on-a-spring". I am doing some deliberate oversimplification of the model; my goal is aesthetic, not engineering.

  • $\begingroup$ And about your problem... Georg put it right that it is too complex to try to do it good if you only want aesthetic effect. Try asking on gamedev.stackexchange.com (I would migrate, but I think now it would be more confusing than helpful). $\endgroup$

  • $\begingroup$ @mbq: Okay, thank you! I'll try to put together a more simulation-oriented question for gamedev after I look into Georg's links. As I said, please close if you think this is off-topic for physics.stackexchange. $\endgroup$
