| Abstract: |
We have developed a numerical package for simulations of dusty proto-planetary disks. We solve the fully coupled gas and dust dynamic equations. We also explicitly include the turbulent viscosity in gas dynamics and turbulent diffusion in dust dynamics. We propose a new modified momentum equation for the dust dynamics by removing some anti-diffusion terms. This new modification avoids the potential instability caused by the diffusion term in the dust transport equations. Numerical results demonstrate our proposed modification is effective. |
