Mixing of reagents in microfluidics is critical, and currently, the focus on Newtonian fluids, but these are often viscoelastic fluids. In this study, a micromixer containing conductive cylinder proposed based principle induced charge electro-osmosis (ICEO). The Oldroyd-B constitutive model was chosen to characterize flow properties Poisson–Boltzmann used describe ion distribution electrolyte. impact elasticity number (El) fluids mixing efficiency, velocity, vortex studied. results show that...
Micromixers have important applications in lab-on-a-chip, biomanufacturing, and chemical engineering. In this study, a micromixer with conductive barrier plate based on the induced charge electro-osmosis is proposed. The Oldroyd-B constitutive model was chosen to characterize flow characteristics of viscoelastic fluids, Poisson–Boltzmann used electrokinetic properties. effects installation plate, concentration polymer, shape mixing were studied finite volume method. efficiency fluids 78.3%...
Enhancing the micro-channel flow mixing is always a difficult problem. In this study, micromixer based on induced charge electro-osmosis proposed. A T-shaped micromixer, which has chamber with conductive surfaces in channel, chosen. Due to electro-osmotic effect of charge, potential generated surface. The Oldroyd-B constitutive model chosen characterize characteristics polyacrylamide solution, and an open-source solver named rheoTool finite-volume method used. shape, size, edge numbers...
Effective mixing at the microscale is crucial in bioengineering and chemical engineering. In this study, of viscoelastic fluids described by Oldroyd-B constitutive model micromixer with a conductive cylinder was numerically studied. Based on finite volume method, EDL effect approximated slip velocity surface using Helmholtz-Smoluchowski theory. The effects polymer concentration applied electric field intensity polyacrylamide (PAA) solutions were investigated. results show that decreases...
