Non uniform viscosity
Hello, I'm trying to sovle a problem related to water droplet. According to the shape change of the droplet, I want to calculate velocity.
In this case, the viscosity and density are not uniform. I mean water and air. Then, how can I handle it.
In most codes, they just need one Re.
Re: Non uniform viscosity
Are you interested in the velocities of both the air and the fluid? Or just the fluid? You will need to solve for the interface, and then both flows are determined by matching stresses along the boundary between them. So, the answer to your question depends on what you are trying to do, and by what means you are trying to solve your system of equations. Say more, perhaps?
