Modeling and Flowsheet Simulation of Vibrated Fluidized Bed Dryers

Application of three Types of Dryers Namely Tunnel, Fluidized Bed, and Fluidized Bed with Microwave for Drying of Celery, Corn, and Sour Cherry: Experiments and Modeling (TECHNICAL NOTE)

In this paper, water content from celery, corn, and sour cherry were removed through tunnel, fluidized bed, and fluidized bed with microwave dryers. One day before performing the experiments, the fruits were put into a refrigerator and were ground into slices with average dimensions of 5×8×8 mm. For each experiment, 40 g of the samples were inserted in dryers. Moisture content in the samples wa...

Biomass Gasification in Fluidized Bed Gasifiers Modeling and Simulation

Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed. In order to develop such model for the gasifier, as the ma...

Numerical study of heat transfer in fluidized bed dryers by volume of fluid ‎method

The purpose of this study is numerical modeling of temperature variation of phases in a two phase regime in fluidized bed dryers including particles belonging to Group D of geldart classification. The mass transfer between phases is not taken into consideration in this modeling which has been assumed in three- dimensional, unsteady, and two-phase regime.To verify the modeling we consider the do...

Improving Three Phase Modeling of Fluidized Bed Dryer

Heat transfer phenomena in batch fluidized bed dryer have been studied and analyzed using three phase model including solid phase, interstitial gas phase and bubble phase based on Rizzi model. New correlations of heat transfer coefficient to surrounding and convection heat transfer coefficient between solid and interstitial gas are being proposed. In addition, some modifications have been d...
