Prediction of the packed bed height in liquid-solid semi-fluidization of homogeneous mixtures

Hydrodynamics of regular particles in a liquid–solid semi-fluidized bed

“…Almost all values are within 15% of the experimental ones in case of these equations. The recommendation for the use of two different power law correlation for the two different range of the values of (h − h pa )/(h − h s ) by Mydlarz [26] is found to be true as it is seen from Fig. 14.…”

“…Mydlarz [26], from his experimental finding has shown the validity of Eq. (14) for the range of the dimensionless packed bed height as;…”

Hydrodynamics of Liquid-Solid Semi-fluidized Bed with Regular Homogenous Ternary Mixture

“…4 (9) In Figure 14, the experimental values of ΔP sf /ΔP mf have been compared with the calculated values obtained from Eq. (9). The values of standard deviation and correlation coefficient are 0.55 and 0.993.…”

“…Of late, hydrodynamic investigations relating to mixtures (binary/ternary) of homogenous or heterogeneous nature has become essential in view of their potential applications in slurry and gas-solid reactions. A few articles on hydrodynamic characteristics of liquid-solid binary homogenous and heterogeneous mixtures in semifluidization have been reported [1,5,9,10]. The use of mixtures have the advantages in semi-fluidization as with less pressure drop both fluidized and the packed bed condition can be achieved compared to a particle [1].…”

Biodiesel synthesis using immobilised lipase enzyme in semi‐fluidised bed bioreactors—bioreactor design and performance analysis

“…Experimental correlations have also been developed for the computation of the height ratio of the packed section to fluidised section of liquid–solid semi‐fluidised beds by many authors such as Kurian and Raja Rao , Roy and Sharma , Singh et al . and Mydlarz . Based on repeated trials, the correlation proposed by Singh et al .…”
