Evaluation of Strategies for Temperature and Moisture Control in Solid State Packed Bed Bioreactors
Different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. The experiments were carried out within a 1-L solid-state packed bed bioreactor in which Aspergillus niger was cultivated on wheat bran....
متن کاملTransient 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...
متن کاملBehavior of Packed Bed Thermal Storage
A packed bed thermal storage has several desirable characteristics to be used for energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (K1), conduction effect (K2) and air capacita...

متن کاملAdiabatic Reverse Combustion in a Packed Bed
Downward propagation of a combustion front in a packed bed of wood particles, with air supply from below, is examined theoretically and experimentally. Using a single-step reaction, with a kinetic model of char oxidation as the dominant mechanism, and assuming local thermal equilibrium, but allowing a local chemical nonequilibrium between the solid and gas phases, the front speed u F, the adiab...
