Flow through Packed Beds and Fluidized Beds
Chemical engineering operations commonly involve the use of packed and fluidized beds. These are devices in which a large surface area for contact between a liquid and a gas (absorption, distillation) or a solid and a gas or liquid (adsorption, catalysis) is obtained for achieving rapid mass and heat transfer, and particularly in the case of fluidized beds, catalytic chemical reactions. You wil...
متن کاملInfluence of rheology on debris-flow simulation
Systems of partial differential equations that include the momentum and the mass conservation equations are commonly used for the simulation of debris flow initiation, propagation and deposition both in field and in laboratory research. The numerical solution of the partial differential equations can be very complicated and consequently many approximations that neglect some of their terms have ...

متن کاملExperimental study on the rheological behaviour of debris flow
A model able to describe all the processes involved in a debris flow can be very complex owing to the sudden changing of the material that turns from solid into liquid state. The two phases of the phenomenon are analysed separately referring to soil mechanics procedures with regard to the trigger phase, and to an equivalent fluid for the postfailure phase. The present paper is devoted to show t...
متن کاملAssessing Debris Flow Hazard by Credal Nets
Debris flows are among the most dangerous and destructive natural hazards that affect human life, buildings, and infrastructures. Starting from the ’70s, significant scientific and engineering advances in the understanding of the processes have been achieved [4, 7]. Yet, human expertise is still fundamental for hazard identification, as many aspects of the whole process are poorly understood; a...
