CFD simulation and experimental study for two-phase flow through the trickle bed reactors, sock and dense loaded by trilobe catalysts

Numerical and Experimental Study of Catalyst Loading and Body Effects on a Gas‐Liquid Trickle‐Flow Bed

“…Propp et al [19] considered the effect of porosity distribution and capillary pressure in a 2D frame with the porous media approach as well. Bazmi et al [29] reported the hydrodynamics in a two-phase packed-bed reactor with trilobe catalysts utilizing a three-phase approach as well. Holub et al [20], Al-Dahhan and Dudukovic [21], and Larachi et al [22] implemented a slit model to simulate a two-phase flow utilizing a three-phase approach.…”

CFD simulation and experimental study of liquid flow mal-distribution through the randomly trickle bed reactors

“…First, the volume of catalyst pore is measured with mercury under the pressure of 2000 bar and then, the bulk porosity of a limited amount of catalyst is determined by using Ultra Porosimetry technique. According to this technique which has been previously described in detail by Bazmi et al [37], the calculated bulk porosity of dense and sock packed beds are 0.42 and 0.46, respectively.…”

“…For defining and implementing porosity distribution in the CFD model, the average bed bulk porosity and the radial variation on porosity should be determined. Bazmi et al have investigated the porosity distribution of trilobe catalyst in trickle bed reactors by using the (X-ray computed tomography) CT scan imaging technique [37]. They also have measured the average bulk porosity for trilobe catalyst loaded bed.…”

“…In this study the same catalyst and bed have been used for investigation of flow mal-distribution. The following correlation which is a function of particle diameter and radial distance from the wall has been applied for trilobe catalysts in the CFD simulation [37]: where;…”

Validation of a novel open-source work-flow for the simulation of packed-bed reactors

“…cylinders and trilobes) can be treated only with cumbersome strategies. This is particularly important because these exotic shapes, such as trilobes, are becoming more and more popular [27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Other interesting alternatives are based on the use of Monte Carlo methods [41][42][43] that solve some of the above mentioned issues.…”
