It doesn't seem like the wet bulb model accounts for ratio of surface area and volume. The instrument they use is the sling psychrometer, a long cylindrical tube [1]. If I had to hazard a guess, the ratio of surface area to volume is much higher for the bulb than it is a human. Evaporative cooling is a function of surface area--more surface area => more cooling capacity. I'd be curious to see how accurate the model if the surface area to volume ratio were more human-scale. 1. https://www.sciencedirect.com/topics/engineering/sling-psychrometer https://www.sciencedirect.com/topics/engineering/sling-psych...
