A mathematical model for continuous fluidized bed drying
TLDR
In this article, a mathematical model for continuous drying process in a fluidized bed-dryer is presented to describe the heat and mass transfer in gas phase, a Kunii-Levenspiel type, three-phase model representing a dilute (bubble) phase, interstitial Ga Numerical computation based on this model was done to study the effects of the process parameters as particle and bubble-size, gas velocity, inlet gas.About:

Fluidized Bed Dryers — Recent Advances
TL;DR: A combination of multi-phase models and residence time distribution could improve predicting power for back-mixed dryers because this combination takes into account both the bubbles and solid mixing phenomena.
Journal ArticleDOI
Investigation of batch fluidized-bed drying by mathematical modeling, CFD simulation and ECT measurement
TL;DR: In this paper, a three-phase theory that describes the mass and heat transfer between the air and solids phases is used to develop an understanding of batch fluidized-bed drying, which is a complex air-solids, multiphase process.

Steam drying of coal. Part 2. Modeling the operation of a fluidized bed drying unit
TL;DR: In this paper, a mathematical model was developed for the continuous drying of a single porous particle in steam, which was integrated with a two-phase hydrodynamic model to simulate the continuous coal drying in a bed fluidized with superheated steam.

Wärme‐ und Stoffübertragung in der Wirbelschicht
TL;DR: In this article, a new model was developed for the wall-to-bed heat transfer from solid surfaces immersed in fluidized beds, which makes use of some basic ideas adopted from the kinetic theory of gases in order to describe the mechanism of energy transfer through the moving particles.

Mathematical model for spray drying
M. Parti,B. Palancz +1 more
TL;DR: In this article, a mathematical model for dimensioning spray driers is developed for the dimensioning of spray drippers. But the model is not applicable to porous particles and does not take into account the solidifying of the surface of the spray dripper.

Mechanisms of heat transfer between a surface and a gas-fluidized bed for combustor application
S.C. Saxena,J.D. Gabor +1 more
TL;DR: In this paper, the authors present a review of the major mechanisms of heat transfer in coal combustion, focusing on two main schools of thought: (a) the principal resistance to heat transfer is a fluid film, and the moving fluidized particles scour the film to reduce the resistance of the heat transfer; and (b) heat is absorbed by the fluidised particles and the rate of heat transferred depends on the rates of heat absorption.

Analysis of a model for a nonisothermal continuous fluidized bed catalytic reactor
TL;DR: In this paper, a three-phase model, consisting of a dilute or bubble phase, an interstitial gas phase and a solids phase, was developed for a non-isothermal gas fluidized-bed catalytic reactor with continuous circulation of catalyst particles.
