The transition from the fixed to the fluidized state of well‐mixed binary‐solid mixtures in a liquid upflow

open access: yesAIChE Journal, EarlyView.
Abstract In this work, an investigation of the transition from fixed to fluidized state of initially homogeneous binary‐solid mixtures due to an upward liquid flux was carried out. Like for analogous gas systems, it was confirmed that the full transition occurs over a range of fluid velocities, from the initial to the final fluidization velocity. Based

Dynamic Friction Model for the Investigation of Stick‐Slip Oscillations

open access: yesChemical Engineering &Technology, Volume 46, Issue 1, Page 29-36, January 2023., 2023
An efficient dynamic friction model based on the Stribeck curve is presented, which allows to investigate the influencing parameters on the stick‐slip effect through finite element simulations. The simulation of a tribometer test proofs that the model correlates well with the tribometer test results.

Physics‐informed neural networks (PINNs) for high‐resolutional prediction of shear stress on cells in suspension culture

open access: yesAIChE Journal, EarlyView.
Abstract The effect of shear stress on cell behaviors should be considered for designing the suspension culture of mammalian cells. Computational flow dynamics (CFD) is a promising tool for estimating shear stress on cells, but the accuracy is limited due to resolution limitations.

Modeling of Crescent‐Type Internal Gear Pumps Considering Gear Radial Micromotion

open access: yesChemical Engineering &Technology, Volume 46, Issue 1, Page 128-136, January 2023., 2023
A numerical approach for investigating crescent‐type internal gear pumps, coupling a lumped parameter pressure solver with a CFD film simulator based on transient gap geometries solved from gear loading forces was proposed. Volumetric efficiency prediction was validated by measurements.

Aerodynamics of Harmonically Oscillating Aerofoil at Low Reynolds Number

open access: yesJournal of Aerospace Technology and Management, 2017
Two-dimensional flows over harmonically oscillating symmetrical aerofoil at reduced frequency of 0.1 were investigated for a Reynolds number of 135,000, with focus on the unsteady aerodynamic forces, pressure and vortex dynamics at post-stall angles of ...

Investigation of CAST-10-2/DOA 2 airfoil in NAE high Reynolds number two-dimensional test facility [PDF]

open access: yes
A common airfoil model with the CAST 10-2/DOA-2 profile and 228 mm (9 inches) chord length was tested. The tests performed in NAE covered the Mach numbers from 0.3 to 0.8 and Reynolds numbers from 10 to 30 million.
