Gas migration in oil and gas wells is defined as gases and/or fluids from adjacent formations
invading a freshly cemented annulus. During well completions, gas and/or fluids can migrate …

The ability of a gel to act like a solid-like material at rest and flow like a liquid when sheared
can be very useful in propulsion system. Numerical simulation of the flow of gel fuels can be …

Linear temporal stability of an ideal thixotropic fluid obeying the Moore model in a flat plate
boundary-layer flow is investigated in the present work. The Moore model captures the …

When a less viscous fluid displaces a more viscous fluid, the interface between the two fluids
becomes unstable. The instability exhibits itself as a large number of fingers of the …

Additives such as nano-silica and fly ash are widely used in cement and concrete materials
to improve the rheology of fresh cement and concrete and the performance of hardened …

The pulsating flow plays a potential role in improving the heat transfer performance of ice
slurry. However, the flow resistance characteristics of ice slurry in pulsating flow have not …

Casing eccentricity reduces displacement efficiency during horizontal well. However, there
are many problems such as the short length of horizontal well simulation and long …
