I have a reaction vessel for a chemical process. The vessel has a poly base with a stamped recess and is covered by a poly adhesive film. The vessel contains water with an air gap. The vessel reaches temperatures of 95°C.
Things I want to model:
- Pressure increase from the expansion of air (think ideal gas law) due to heating
- Increase of vapor pressure in air pocket due to the water due to heating.
- Deformation of both poly parts due to increasing internal pressure and constant ambient pressure
- Stress on adhesive "weld" around circumference of reaction vessel.
So items 1 & 2 appear to be CFD simulations and 3 & 4 to be FEA simulations.
Details I want feedback on:
- Transient Thermal Simulation - I plan on having initial conditions of reaction vessel at 20°C with an ambient heat of 95°C
- Pressure Increase of Heated Air - does Flow Sim explicitly model ideal gas law, or do I need to define a pressure relationship relative to temperature?
- Vapor Pressure Increase of Heated Water - I'm planning modeling the water as a free surface. Can Flow Sim explicitly model water evaporation, or again, do I just define the relationship of the pressure vs temperature?
- Interaction of Internal Pressure and Deformation - As the reaction vessel undergoes elastic deformation, the internal volume will increase. This will decrease the internal pressure (ideal gas law) until an equilibrium is reached.
I look forward to hearing your ideas!
