2. Description of the Project
Added convective effect
Simulation based on erosion simulation
Equation: dc/dt=D*laplacian(c)-v*gradient(c)
Velocity field is set unidirectional through entire simulation
Simulation is run much like erosion simulation but contour plot is animated
Areas that represent particle is set with regions with no concentration
Simulation result showed convection had stronger transport power than diffusion
Furthermore, considering experimental understanding of diffusion through porous media, unidirectional velocity field doesn’t work. More complex relationship between fluid velocity and large particle needs to be implemented to give a more realistic result.
