Diffuse-flow, low-temperature areas near hydrothermal vents support life via chemosynthesis: hydrogen sulfide (and other reduced chemical compounds) emanating from the subsurface is oxidized with bott...
Diffuse Flow On and Around Hydrothermal Vents at Mid-Ocean Ridges
Around Hydrothermal Vents Mid-Ocean Ridges
2015/7/14
Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor. However, not all seawater that circ...
Numerical diffusion for flow-aligned unstructured grids with application to estuarine modeling
unstructured grid numerical diffusion grid generation grid alignment
2015/6/30
The benefits of unstructured grids in hydrodynamic models are well understood but in many cases lead to greater numerical diffusion compared with methods available on structured grids. The flexible na...
