MRT-Lattice Boltzmann Model for Multilayer Shallow Water Flow

Kevin R. Tubbs, Frank T.-C. Tsai
2019 Water  
The multilayer MRT-LBM is promising for simulating lateral and vertical distributions of the horizontal velocities in shallow water flow.  ...  Using multiple relaxation times in the lattice Boltzmann model has an advantage of handling very low kinematic viscosity without causing a stability problem in the shallow water equations.  ...  Each layer has an initial local water height of 1 m, such that initial water depth is 10 m. The initial flow velocity is zero.  ...

Pretreatment Techniques for Produced Water with Subsequent Forward Osmosis Remediation

Tiffany Liden, Zacariah L. Hildenbrand, Kevin A. Schug
2019 Water  
It can be concluded that forward osmosis can be used to extract water from high-salinity oil field brines and produced water, and that pretreating the produced water decreased the tendency for fouling.  ...  Forward osmosis is a viable option to treat high-salinity produced water; however, fouling has been an issue.  ...  Solaris Water Midstream is also gratefully acknowledged for providing PW samples. UltraPAC coagulants and polymer were provided by Geochemicals.  ...
