Capillary flow simulation
 

hi, i want to simulate the fluid flow in the capillary groove, the curvature of the liquid-vapor interface changes continualy along the axial length of the groove because of the evaporation,the flow is driven by the curvature difference of the liquid. The flow is laminar. The vapor-liquid interface is free surface, governed by Young-Laplace equation.

i do not know if CFD can simulate this,what's the name of the package. if someone has modeled the similar case, please give me some advice.

thanks in advance.
