We observe that where mushroom-like plumes are observed for lower viscosity ratios, taller plumes with bulbous heads form for high viscosity ratios.
Accuracy is diminished at more extreme viscosity ratios when the less viscous fluid is in a thin layer.
Finally, simulations showed a wider distribution of surfactant on the interface for smaller viscosity ratios.
Many conditions apply to this scaling equation, including identical core sample shapes and fluid viscosity ratios.
We show that small viscosity ratios lead to more efficient displacements, as is intuitive.
This was stronger at low viscosity ratios than at high ratios.
A wide range of Ohnesorge numbers and density and viscosity ratios of two fluids are tested.
In the calculation, various viscosity ratios between thermoplastics and LCP components were applied.
It allows numerical simulations for a wide range of viscosity ratios and density ratios.
Experimental results cover a range of viscosity ratios of over seven orders of magnitude.
Increasing the volume fraction, however, increased the thermal conductivity coefficient and viscosity ratios, and increasing the Nusselt number also increased the convective heat transfer coefficient.
