Hello former,
I wanna solve the temperature distribution in metal tank while emptying its hot containment.
Attached Geometry.PNG shows its physical shape.
Situation is - Initial: liquid is stored in tank, outlet is closed, heat exchange occurs among liquid, solid, and atmosphere.
- Emptying: whole tank is tilted and outlet is open. Liquid escapes the tank trough gravity driven flow.
- Final: outlet is closed again, tank return horizontal position.
My approach so far is following - Add a couple of baffles between tank(purple) and outlet(orange)
- Assign activePressureForceBaffleVelocity boundary condition for baffles
- Add time dependent body force to simulate dumping out the tank
- Pressure changes due to body force allows liquid flow through baffles
My questions are: - My approach is applicable for given situation?
- Is there any tutorial or case study that I can refer? Especially for time dependent body force part, I wanna a tutorial for fvOption.
- Or any case where emptying a container after some turning point(by opening closed outlet)
