A correlation for the prediction of packed bed height in liquid—solid semi-fluidization

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

“…Singh et al [25], have proposed a different correlation in the logarithmic form from their experimental finding as indicated below.…”

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

“…As stated earlier, the height of the packed section ( ) and that of the fluidised section ( ) are estimated from one of the selected correlations reported in literature, such as that proposed by Singh et al . .…”

“…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 .…”

“…Based on repeated trials, the correlation proposed by Singh et al . has been selected for utilization in the present analysis.…”
