Droplet Transfer in Two Phase Annular Mist Flow : Part 2, Prediction of Droplet Transfer Rate
The liquid droplet transfer onto the duct wall was studied experimentally in the previous paper, part 1. In the present paper, a method for predicting the droplet transfer rate is proposed. The droplet transfer coefficient is expressed theoretically in terms of the duct height, the eddy diffusivity and scale of turbulent motion of droplet based on an ...

Heat Transfer by Sweat Droplet Evaporation
Sweating regulates the body temperature in extreme environments or during exercise. Here, we investigate the evaporative heat transfer of a sweat droplet at the microscale to unveil how the evaporation complexity of a sweat droplet would affect the body's ability to cool under specific environmental conditions.
