I have modeled a simplified thermoelectric cooler dehumidifier setup with a inlet fan and a heat sink on both hot and cold sides of the TEC. The temperature results on the heat sinks are in the range of what I was expecting from hand calculations so I think I have the basic simulation working. What I would like to be able to do is compare latent heat vs sensible heat for a various inlet temperature and humidity conditions. I can see the humidity reaching 100% as it cools over the cool side heatsink but is there any way to simulate the amount of moisture from the air that condenses?
there is no phase change in flow simulation
there is also no surface moisture
however if you are using humidity, if the air cools, it will affect the fluid properties in the way that you want (i think based on your description)
