On the Pressure Drop Through a Uniform Snow Layer
Abstract
An experimental study covering a mass flow rate ranging from 1 .62 to 67.45 g/sq cm-s and snow density varying from 0.377 to 0.472 g/cu cm has been conducted. Pressure drops ranging from 0.012 to 2.868 g/sq cm were recorded. A plot of the friction factor f sub p vs Re sub p (defined as the classical Reynolds number Re for fluid flow through conduits) showed a good representation of all the experimental data. The least-squares analysis resulted in an expression of f sub p = 118/Re sub p to the 1.095 power for snow, in comparison with the expression f sub p = 64/Re sub p developed for fluid flow through porous media of randomly packed metallic and nonmetallic materials of spherical and nonspherical shapes. Keywords: Air flow; Thermal conductivity; Vapor diffusivity; Fluid flow; Friction coefficient; Porous media.
