Prof. Hamid Ait Abderrahmane Received his Ph.D. from Concordia University, Montreal, Canada, in 2009. Prior to joining Khalifa University, he was a Postdoctoral Fellow at McGill University, Canada and Postdoctoral Fellow at King Abdullah University of Science and Technology (KAUST), Saudi Arabia.  His research interests is in the areas of the general fields of fluid mechanics and fluid-structure interactions with a particular focus on nonlinear dynamics in fluid-structure interactions and hydrodynamic instabilities. He was awarded the two prestigious Postdoctoral Scholarships in Canada and Quebec. His Ph.D work was honored as one of the top 10 discoveries of the year (2009) by Quebec Science Magazine. His work on flow visualizations received the prestigious Milton Van Dyke Award, Gallery of Fluid Motion (2010). Dr. Hamid Ait Abderrahmane has published 41 research papers in top-notch journals including Physical review letters, Journal of Fluid Mechanics, Physics of fluids, Physical review E, and 45 papers in international conference proceedings. Apart from his research involvement Dr. Hamid Ait Abderrahmane served for many years as Teaching assistant and Lecturer of various courses at university level.

Recent Research Projects

  • Fluid-structure interactions
  • I am using a filament and soap tunnel as canonical set-up to investigate the nonlinear dynamics of fluid-structure interactions. This research has broader impact in various fields including biofluids (biofilm streamers) and ecosystems (transport of nutrients).

  • Interfacial flows

The flow of a viscous fluid film is a canonical problem for a broad class of engineering, and biomedical applications. Examples include coating of organic solar panels, tear film dynamics and digestion dynamics at the level of the stomach.

  • Swirling flows.

I am interested in the instabilities of swilling flow, in particular those leading to the formation of helical tip vortices and vortex patterns. These instabilities are of primary importance in various fields of current interests such as aerospace industry (aircrafts and helicopters), sustainable energy (wind turbines), naval industry (ship propeller) and turbomachines. I am also interested in phenomenon of solitons in swirling flows. These solitons appear as bifurcation solutions, when the fluid depth of swirling fluid reaches a shallow water conditions or during vortex decay.

  • Geophysical flows

I am interested in mimiking some fascinating geophysical flows such spiral arm galaxies and collision of two black holes at the scale of the laboratory. I am attempting to replicate gravitational waves that follow the collision of two black holes (two singularities) thought the merging of two “point vortices” (two singularities) using shallow water theory and fluid dynamics analogy. I am also attempting to explain the flatness of rotational curve of the spiral galaxies through fluid analogue experimental model of the circular hydraulic jump.

  • Foam and multiphase flows in porous media

This research falls under the umbrella of the worldwide ongoing research on foams and their applications in soil decontamination operations, CO2-foam enhanced oil recovery (EOR).
