droplet rebound simulation

[CKJK]

Hello, I am trying to simulate a droplet rebound process. I found what I simulated did not feel very real. I gave density, viscosity, eos, and elasticity. First, the droplet merely deformed as it strikes the aluminum plate. It should become less spherical as it contacts the plate? Besides, based on some scientific theories, the rebound should be higher than original starting point if the viscosity is very high, while the height is lower than the original point if the viscosity is low. However, no matter what viscosity value I gave, the height always was lower than the original starting height.

Hope someone can take a look at my file, and suggest how to optimize my simulation to make it more realistic~

Thanks a lot in advance!!

What is the source of material properties used in this simulation ? Are they from the article from which the attached picture was taken ? Can you share the title of this article ?

I only used the viscosity range in this paper as my reference, other properties are water's density, elasticity and eos values.
The title of article is "The viscosity of atmospherically relevant organic particles"

Is it the size of my water droplet affected the result?

I think that you should focus on material properties (especially elasticity). You may have to adjust them to achieve the expected result.

Thanks a lot! I reduced the elasticity and it indeed deformed like a droplet upon striking the plate. But, the rebound height still did not change while the viscosity was raised largely. What parameters do you think can change rebound fraction?
