lotus leaf !!!

ram

hi.. this may appear naiev..but its worth thinking..i am modelling flow of water pearls on lotus leaf..as u all know that water doesnt stick to the leaf. how should i introduce this bc in the NS equations. i want to check out at which angle does the water pearls fall off the leaf if inclination of leaf is increased gradually w.r.t. the horizontal. and i want to check the frequency at which the large water pearl will break into small pearls if i vibrate it artificially. how do i introduce this frequency term in the NS equations? Should it go in the source term ?

Thank you
