WebAbstract. Based upon a simple model for the transport mechanism, equations are developed for the prediction of the equivalent heat conductivities of packed beds. The predicted values agree well with the values of the equivalent heat conductivity determined experimentally for various flow rates through different packing materials. Web1 de nov. de 1998 · This paper presents results from a detailed experimental investigation of the heat and mass transfer between a liquid desiccant (triethylene glycol) and air in a packed bed absorption tower using high liquid flow rates. A high performance packing that combines good heat and mass transfer characteristics with low pressure drop is used. assassins 3WebEddy mass diffusivities, effective thermal conductivities, and wall heat transfer coefficients were measured in an 8-in. tube packed with 1/2- and 3/4-in. glass spheres. Superficial mass velocities ranged from 110 to 1,640 Ib./ (hr.) (sq. ft.), corresponding to modified Reynolds numbers of 100 to 2,000. Air was the main stream fluid in all cases. la mesa omaha emmet
