Relating Modified Ergun's Equation To Hindered Settling Correlations, Ryan Zahniser
Relating Modified Ergun's Equation To Hindered Settling Correlations, Ryan Zahniser
Williams Honors College, Honors Research Projects
Correlations were developed between the Modified Ergun’s and Hindered settling correlations under the condition of dense packing of particles in the bed. As the porosity of the slurry increases, so does the interference between particles in the solution which mimics the behavior of a packed or densely concentrated fluidized bed. The similarity between the two sets of conditions was modeled using mathematical equations to calculate settling velocities and pressure drops by means of the Hindered Settling correlations and Modified Ergun’s equation at porosities ranging from 0.4242 to 0.89. The results showed that a porosity of 0.52 and 0.009 ft particle …
