hi. i want to simulate Al2o3 - water nano fluid in a 2D canity (1*1)
*Diameter of Al2O3=40nm. so volume of one particle=3.35E-23 m^3 (spherical particle)
*if depth of cavity be 1m (set at reference value), volume of cavity should be 1m^3.
*for 0.04 volume fraction of nano particle, total volume of nano particle should be : 0.04*volume of cavity=0.01 m^3
*finaly the number of nano particle should be: 0.04/volume of one particle=1.19E+21
my question is how can i set this number of particle in a cavity?
