Summary

The simple control of energy conversion in a thermal reactor has a negative impact on the environment, as a result of 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 paper is concerned with the optimization of the operation of energy equipment and prevention of their dysfunction. The objective of this study is the development of experimental method for characterization of gas flows in order to detrmine the residence times distribution for gaseous phases. On the other hand, developing a numerical model that combines both a discrete granular behavior using the discrete element method and the approach of computational fluid dynamics thus allowing optimization and extrapolation facilities on an industrial scale to mitigate the shortcomings observed in the reactors such as, dead zones or poor fluidization, short circuits, etc. The first approach proposed is based on a finite volume computational fluid dynamics modeling of the behavior of a single-phase fluid, this model allows us to obtain the trajectory of a particle and the residence time distribution. The experimental study performed in parallel, allows us to validate our numerical model and apply it to other configurations.
