Correlations for the Interphase Drag in the Two-Fluid Model of Gas--Liquid Flows through Packed-Bed Reactors
Pranay P. Nagrani, Amy M. Marconnet, Ivan C. Christov
Experiments conducted by NASA measured the pressure drop due to gas--liquid flow through a packed-bed reactor under microgravity conditions. From these experiments, we develop corr…
Hydrodynamics of bubble flow through a porous medium with applications to packed bed reactors
Pranay P. Nagrani, Amy M. Marconnet, Ivan C. Christov
Gas-liquid flows through packed bed reactors (PBRs) are challenging to predict due to the tortuous flow paths that fluid interfaces must traverse. Experiments at the International…
Two-fluid modeling of heat transfer in flows of dense suspensions
Pranay P. Nagrani, Federico Municchi, Amy M. Marconnet +1
We develop a two-fluid model (TFM) for heat transfer in dense non-Brownian suspensions. Specifically, we propose closure relations for the inter-phase heat transfer coefficient and…
A two-fluid model for numerical simulation of shear-dominated suspension flows
Federico Municchi, Pranay P. Nagrani, Ivan C. Christov
Suspension flows are ubiquitous in nature (hemodynamics, subsurface fluid mechanics, etc.) and industrial applications (hydraulic fracturing, CO storage, etc.). However, such f…
