Özet:

The simple control of energy conversion in a thermal reactor has a negative impact on the environment, due to the emission of greenhouse gases. It is also related to energy consumption, which is important for weak yields, and creates problems for reacting flows. The present contribution aims to optimize the operation of energy equipment and prevent their dysfunction.The objective of this study is the development of experimental method for characterization of gas-solid flows in order to detrmine the residence times distribution (RTD) for solid and gaseous phases [1]. On the other hand,developing a numerical model that combines a discrete granular behavior Discrete Element Method (DEM) andtype of approach continues, Computational Fluid Dynamics (CFD) [2], thus allowing optimization andextrapolation facilities of an industrial scale to mitigate the shortcomings observed in the reactors such as, deadzones or poor fluidization, short circuits, etc... Our first approach is based on a finite volume CFD modelling ofthe behavior of a single-phase fluid; this model allows us to obtain the trajectory of a particle and the residencetime distribution. The experimental study performed in parallel, allows us to validate our numerical model andapply it to other configurations.
