Amplification of rectangular spouted beds by jet deflection

Abstract

Spouted beds were first proposed in the 1950s, and have been refined and updated in various ways, and are now in their development period, but there are still problems with jet deflection. This study takes the rectangular spouted bed as the object and systematically analyzes the influence of the nozzle position on the particle movement behavior and jet deflection and distribution. Setting three cases with different nozzle position which D=0.12 m, D=0.14 m and D=0.16 m. Then each run for 50 seconds and then find the optimal nozzle position with compared the result such as particle distribution and residence time. The simulation results show that the appropriate optimization of the nozzle position can significantly reduce the jet deflection phenomenon and improve the uniformity of particle distribution. This complete design not only ensures the Controllability of experimental conditions but also provides a reference for the construction and optimization of future small-scale test devices. The characteristics of this study are setting different nozzle positions in the system to obtain comprehensive comparative analysis results, third combing simulation with engineering design, take into account both theoretical research and actual application which reflecting a high degree of maturity and engineering feasibility.
