Experimental investigation of drag reduction by polymer additives in a turbulent channel flow
DownloadSpring 2018
The addition of a minute amount of long-chain polymer molecules to a turbulent flow can cause a significant reduction of skin-friction drag in both internal and external flows. The explanation of interaction between polymers and turbulence remains the most difficult area of polymer flow...

Experimental Investigation of Near-well Fluid Mechanics on the Scaling Mechanism in Narrow Rectangular Slots
DownloadSpring 2020
This experimental study investigates the effect of near-well fluid mechanics on the scaling failure mechanism specific to SAGD production well. The scaling failure mechanism can be triggered by the pressure drop phenomenon and causes the plugging of the slots in the oilfields. The scale formation...

Experimental Investigation of Viscoelastic Cavitating and Turbulent Channel Flows Subjected to Different Pressure Gradients
DownloadSpring 2023
Steam-assisted gravity drainage is a common method for oil production in Alberta, Canada. Production wells are equipped with inflow control devices to improve production efficiency. These devices utilize nozzle-type constrictions to enhance oil production by hindering water and gas breakthroughs....

Experimental Investigation on the Turbulence of Particle-Laden Liquid Flows in a Vertical Pipe Loop
DownloadSpring 2016
The turbulent motion of particles and their interactions with the turbulence of the carrier phase make a complex system. Hence understanding the physics and consequently developing a well-stablished model becomes very difficult. With insufficient computational power to numerically resolve all the...

EXPERIMENTAL STUDY OF THE GEOMETRIC CHARACTERISTICS OF BUBBLES/DROPLETS PASSING THROUGH A PORE SPACE
DownloadFall 2021
The multi-phase flow motion of droplets and bubbles through porous media has been reported for different applications. The importance of the effect of the presence of emulsions on the performance of steam-assisted gravity drainage (SAGD) for oil extraction is discussed as a relevant process. SAGD...

Experiments investigating momentum transfer, turbulence and air-water gas transfer in a wind wave tank
DownloadSpring 2011
A series of laboratory experiments were conducted at three fetches of 4.8, 8.8 and 12.4 m, and at six wind speeds ranging from 4.1 to 9.6 m/s at each fetch in a wind-wave-current research facility. In addition, five surfactant-influenced experiments were conducted at concentrations ranging from...

Internal gravity waves transport energy and momentum in both the atmosphere and the ocean. This physical process occurs at such small length scales that it is not captured by coarse resolution numerical models of weather and climate. A series of experiments is presented that model the generation...

Turbulence is a chaotic motion of fluid that can be described by the Navier--Stokes equations or even highly simplified shell models. Under the continuum limit, standard shell models of turbulence are shown to reduce to a common evolution equation that reproduces many predictions of the...
