Pressure Drop of the Air through Packed Wood Fiber Bed

The Prediction of Pressure Drop and Flow Distribution in Packed Bed Filters

A CFD technique for predicting the performance of axisymmetric packed bed filters has been developed. The effect on the pressure drop of a non-uniform voidage distribution within the filter bed has been modelled. A radial voidage distribution was derived from a predictive model based on a modified Mueller equation. The pressure loss through the bed was calculated from the Ergun equation, using ...

Power generation by packed-bed air-cathode microbial fuel cells.

Catalysts and catalyst binders are significant portions of the cost of microbial fuel cell (MFC) cathodes. Many materials have been tested as aqueous cathodes, but air-cathodes are needed to avoid energy demands for water aeration. Packed-bed air-cathodes were constructed without expensive binders or diffusion layers using four inexpensive carbon-based materials. Cathodes made from activated ca...

Experimental Investigations on Packed Bed Solar Air Heater

Transient analysis of incompressible ~ow through a packed bed

The present investigation aims at numerically simulating the temporal energy transport for incompressible ~ows through a packed bed[ The governing equations are formulated according to the volume averaging method[ The generalized momentum equation which accounts for the inertial and viscous forces was used to carry out this research\ whereas the two!energy equation model was used for simulating...

Sizing of a Packed Bed Storage for Solar Air Heating Systems (TECHNICAL NOTE)

Packed bed units generally, represent the most suitable storage units for air heating solar systems. In these systems the storage unit receives the heat from the collector during the collection period and discharges the heat to the building at the retrieval process. A method for sizing of packedbed storage in an air heating system is represented. The design is based on the K-S curves, which hav...
