David M. Warsinger's PhD Defense

Описание: PhD Defense on Thermodynamic Design and Fouling of Membrane Distillation (MD) Systems.
This work comprises 6 core contributions:

For energy efficiency: 1) waste heat entropy generation comparison to 5 other desalination technologies 2) the effect of tilt angle on Air Gap MD (AGMD), and 3) Using superhydrophobic jumping droplet surfaces to enhance AGMD (patent pending)

For fouling: 1) Lit review paper & fouling mitigation methods 2) The effect of filtration and role of bulk nucleation in MD and 3) Using air layers to mitigate MD fouling (patent pending)
