Hey everyone,
I am a third year undergrad in Aerospace engineering.
So i am currently doing a project on showing the interaction between a lunar rover's wheel and the lunar surface. The interesting part about this is that the lunar surface is subject to charging especially in areas that have little contact with solar wing plasma such as craters. As the rover moves across the lunar surface further charge is given to the particles via contact electrification or tribocharging which makes them adhere to surfaces. Because of this, charged dust particles are kicked up and a cloud is formed. I already have a basic simulation on the wheel going across the surface and have implemented the adhesive effect of the particles through the use of Cohesive Energy Density, but this is ultimately hard to get a definitive value and i am aware its usually only used to mimic what we already know, and for my project i want to focus more on the outcome of MY investigation.
My question is more about how would i give a charge (or distribution of charges) to my particles in order to more accurately simulate this effect and how would I simulate the effect of triboelectric charging. I have looked around for information but not come out with much and was wondering if anyone has any experience or could help me or is just interested in the subject and wants to chat more about it. please ask for any additional info relating to this and i will try to provide everything.
Thanks everyone.
