Hi brothers. I simulated the drop flow using phase field method in COMSOl. After simulations, the flow field inside and outside the droplet is uniform and does not change due the interface. Please see the attached file. I am unable to accept these results because the flow field must be different. Could someone explain this problem either my simulations has some problem or the method?.
"...using COMSOL.." There's your problem. You won't learn anything by running one case on some over-rated expensive commercial software package. If you really want to understand the physics of fluid flow, dig deeper and do it yourself.
Thank you Dudley J Benton for your encouragement. I did many cases but could not understand the reason.
Hi Bacha,
I'm not sure what physics you are using. Comsol needs careful implementation if you have moving/deforming domains. It is possible that you are not simulating/post-processing your results correctly.
