The developing flow in a channel filled with porous media
- Nanyang Technological Univ., Singapore (Singapore). School of Mechanical and Production Engineering
When a fluid in a channel (or a duct) flows into a section which is filled with porous materials, it will generally develop into a final form after traveling certain distance from the inlet of the porous section. This entrance flow may affect the heat/mass transfer process in the porous region, and the knowledge of the variation of velocity profile near the entrance will be useful in selection of flow straighteners in flow measurement devices and other applications. The developing velocity profiles of fluids flowing into a porous media were solved analytically for a two-dimensional channel bounded by impermeable walls. Three inlet velocity distributions were considered. The effect of the inlet velocity and the Darcy number on the variation of the velocity distribution was examined and the entrance lengths were determined.
