Designing minimally-segregating granular mixtures for gravity-driven surface flows
Yifei Duan, Jack Peckham, Paul B. Umbanhowar +2
In dense flowing bidisperse particle mixtures varying in size or density alone, smaller particles sink (driven by percolation) and lighter particles rise (driven by buoyancy). But…
Modeling Stratified Segregation in Periodically Driven Granular Heap Flow
Hongyi Xiao, Zhekai Deng, Julio M. Ottino +2
We present a continuum approach to model segregation of size-bidisperse granular materials in unsteady bounded heap flow as a prototype for modeling segregation in other time varyi…
Rejection mechanisms for contaminants in polymeric reverse osmosis membranes
Meng Shen, Sinan Keten, Richard M. Lueptow
Despite the success of reverse osmosis (RO) for water purification, the molecular-level physico-chemical processes of contaminant rejection are not well understood. Here we carry o…
Dynamics of water and solute transport in polymeric reverse osmosis membranes via molecular dynamics simulations
Meng Shen, Sinan Keten, Richard M. Lueptow
The Angstrom-scale transport characteristics of water and six different solutes, methanol, ethanol, 2-propanol, urea, Na+, and Cl-, were studied for a polyamide reverse osmosis (RO…
