Solid adsorption: the missing mechanism for surfactant contact lines -- a phase-field approach
Parvathy K. Kannan, Kazi T. Iqbal, Diego Díaz +5
We develop a thermodynamically consistent phase-field model for soluble surfactants in two-phase flows, incorporating both interfacial and solid surface adsorption. The model is de…
The coherent structures of EVP Fluid Flow Past a Circular Cylinder
Adrián Corrochano, Kazi Tassawar Iqbal, Saeed Parvar +2
This study investigates the impact of elasticity and plasticity on two-dimensional flow past a circular cylinder at Reynolds number . Ten direct numerical simulations wer…
Elastoviscoplastic fluid flow past a circular cylinder
S. Parvar, K. T. Iqbal, M. N. Ardekani +2
The combined effect of fluid elasticity and yield-stress on the flow past a circular cylinder is studied by two-dimensional direct numerical simulation. We analyze the effects of y…
Experimental and numerical investigation of bubble migration in shear flow: deformability-driven chaining and repulsion
Blandine Feneuil, Kazi Tassawar Iqbal, Atle Jensen +3
We study the interaction-induced migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organise into chains aligned in the flow dire…
