The Collison Floating Evaporation Pan: Design, Validation, And Comparison, Jacob William Collison
Civil Engineering ETDs
Accurate tracking of open-water evaporative losses, one of the largest consumptive uses of water in the Southwestern USA, is increasingly important with anticipated climate shifts toward longer and more severe droughts. A new open-water evaporation technique, the Collison Floating Evaporation Pan, (CFEP), was tested on Cochiti Lake, New Mexico, USA for one year with objectives being: identify the limitations and potential solutions to evaporation techniques; deploy, test the reliability, and validity of the CFEP and evaluate uncertainties in standard evaporation techniques; and improvements over prior evaporation techniques. The CFEP provided reliable evaporation measurements during sustained winds greater than 20 m/s. …

Fluid Transport In Porous Media For Engineering Applications, Eric M. Benner
Chemical and Biological Engineering ETDs
This doctoral dissertation presents three topics in modeling fluid transport through porous media used in engineering applications. The results provide insights into the design of fuel cell components, catalyst and drug delivery particles, and aluminum- based materials. Analytical and computational methods are utilized for the modeling of the systems of interest. Theoretical analysis of capillary-driven transport in porous media show that both geometric and evaporation effects significantly change the time dependent behavior of liquid imbibition and give a steady state flux into the medium. The evaporation–capillary number is significant in determining the time-dependent behavior of capillary flows in porous media. …
