The other day I started what I thought would be an easy project of modeling what happens in a clothes dryer but I quickly realized I have no idea what equations to use for mass and heat transfer between the inlet air and the clothes in the dryer. I'm assuming they both depend on the reynolds number of the ventilation air and obviously its heat/humidity but how those factors interact with fabric is something I don't know how to even approximate. And the reynolds number would probably change drastically from when it enters the tumbler to when it runs into the tumbling cloths to when it exits through the exhaust. I tried looking up heat and mass transfer coefficients for fabric in turbulent air and got nothing. Any idea for a good model, close approximation, or even a table with some useful heat/mass transfer coefficients would be super helpful.
