چکیده
Currently, various industrial processes are carried out in fluidized bed reactors. Knowing its internal dynamics is fundamental for the intensification of these processes. This work assesses motion calcium alginate spheres under influence an upward fluid flow within a 1.2 m high and 0.1 inner diameter acrylic column. The liquid–solid was compared with gas–liquid–solid operation mode terms mixing behavior. radioactive particle tracking technique proper methodology to study kinds equipment. Data gathered were analyzed Shannon entropy as dynamic measure. Mixing times found be between 1 2.5 seconds both fluidization modes. presents rather smooth time profile along On other hand, showed sensitivity production height, reaching sharp tendency break at second quartile Glansdorff–Prigogine stability measure can accurately capture regime transitions bed, allowing it used construct reliable operative windows

Hydrodynamics of a Gas-Solid Fluidized Bed at Elevated Temperatures Using the Radioactive Particle Tracking Technique
Effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated. Experiments were carried out in the range of 25-600 ºC and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. Time-position trajectory of particles was obtained by radioactive particle tracking technique. These data were used for determination of mean velocitie...

متن کاملCOMPARISON OF THE EQUATIONS OF STATE FROM JOULE-THOMSON COEFFICIENT
In the present work, we have examined the ability of some different equations of state in predicting the Joule-Thomson coefficient, ?J-T, of different fluids. For dense fluids, for which density is greater than the Boyle density, ?B, two appropriate equations of state, namely the linear isotherm regularity, LIR, and the dense system equation of state, DSEOS, have been examined. The results show...
