Gas-Liquid Hydrodynamics Simulation using CFD in a Helical Ribbon Impeller Applied for Non-Newtonian Fluids
(International Journal of Applied Engineering Research, 2018)
In the present study Computational Fluid Dynamics applied to
non-newtonian fluids was developed in order to characterize
the gas-liquid mass transfer in a 10 L bioreactor equipped
with a helical ribbon impeller. Gas-liquid ...
CFD: A New Challenge in Bioprocess Engineering
(International Journal of Applied Engineering Research, 2018)
Computational Fluid Dynamics (CFD) is a powerful tool
