Abstract: In the quantification of air flow through penetrations in buildings, it is necessary to be able to characterize the flow without detailed knowledge of the geometry of the paths. At the ...

Abstract: A method is presented for estimating lower bounds to the minimum Rayleigh number that will induce a state of convective motion in a quasi-incompressible (Boussinesq) fluid where the temperature ...

Abstract: The energy efficiency of road, rail, and slurry pipeline transportation of mineral concentrates from a potential mine site in northwest Alaska to an ocean shipping terminal is analyzed. Energy consumption rates for ...
