Web•I have gathered, analyzed and processed data to verify relationships in fluid flow (e.g. fluidization of a bed of particles), heat and mass transfer (e.g., linear and radial heat conduction, heat transfer in a double pipe heat exchanger, agitation of water in a cylindrical tank and absorption in a packed column), leaching (e.g., leaching of NaCl - sand mixture … WebThe liberated CO2 is removed from the reactor to external storage. In the exothermic carbonation step, a CO2-containing gas flows through a bed of CaO particles in the reaction zone, forming CaCO3, while CO2-depleted gas leaves the system. The reactor design is refined using a numerical heat and fluid flow model for the calcination step.

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. WebEddy 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.
