VISCOUS FINGERING IN MISCIBLE, IMMISCIBLE AND REACTIVE FLUIDS [PDF]
International Journal of Modern Physics B, 2003 With the Lattice Boltzmann method (using the BGK approximation) we investigate the dynamics of Hele-Shaw flow under conditions corresponding to various experimental systems. We discuss the onset of the instability (dispersion relation), the static properties (characterization of the interface) and the dynamic properties (growth of the mixing zone) of ...

Journal of King Saud University: Engineering Sciences, 2014 Fully developed laminar mixed convection in a corrugated vertical channel filled with two immiscible viscous fluids has been investigated. By using a perturbation technique, the coupled nonlinear equations governing the flow and heat transfer are solved.

Mesoscale modelling of miscible and immiscible multicomponent fluids [PDF]
Scientific Reports, 2019 AbstractA mesoscopic simulation method based on the integration of dissipative particle dynamics (DPD), smoothed particle hydrodynamics (SPH) and computational thermodynamics (CT) has been developed. The kinetic behaviours of miscible and immiscible fluids were investigated.

Angewandte Chemie, EarlyView.Molecular Scissors: Oxide insertion slices the layers of MQ2 transition metal dichalcogenides (TMDs) into one‐dimensional [M3Q6] nanoribbons, giving a new family of A2Hf3Q6O (A = K, Rb, Cs; Q = S, Se) oxychalcogenides. The heteroanion‐driven dimensional reduction yields direct‐gap semiconductors with optical absorption that is tunable across the ...

Start-Up Electroosmotic Flow of Multi-Layer Immiscible Maxwell Fluids in a Slit Microchannel
Micromachines, 2020 In this investigation, the transient electroosmotic flow of multi-layer immiscible viscoelastic fluids in a slit microchannel is studied. Through an appropriate combination of the momentum equation with the rheological model for Maxwell fluids, an ...

Programmable Budding and Fission of Janus Polymersomes for Tunable Cargo Release
Angewandte Chemie, EarlyView.A thermodynamic framework establishes the conditions for the formation of kinetically stable Janus polymersomes using a solvent‐assisted strategy. Osmotic stress subsequently drives their membrane remodeling from reversible budding to controlled fission.
