Flow Dynamics and Stability Laboratory (FDSL)

Flow Dynamics and Stability Laboratory (FDSL)

FDSL is a research laboratory at the Technion, founded by Assistant Professor Yuval Dagan in 2021. The research in FDSL aims to synthesize theory, computations, and experiments to develop new generalized hydrodynamic stability models for multiphase flows in which chemical reactions, turbulence, and particle interactions may be involved.

The laboratory’s infrastructure includes a high-fidelity scientific computing cluster, a high-speed visualization facility for micron-sized surface waves, and a workshop for 3D printed model fabrication. Our research focuses on advancing computational capabilities within the field of aerospace engineering for industrial applications. This work also holds the potential to impact areas such as environmental studies, medical research, and atmospheric studies, particularly in situations involving the dynamics of flow and particles. The Flow Dynamics and Stability group specializes in the following theoretical aspects of fluid mechanics:

  • Theoretical and computational Modeling of Multiphase Flows
    Hydrodynamic instability of reacting and non-reacting particle-laden flows; Settling and diffusion of Brownian particles; Stability of droplets in rotating fluids; Droplet dynamics in vortical environments; Cavitation and bubble growth in metastable fluids under tension; Direct numerical simulations (DNS) of dispersed particulate matter in shear flows; Reduced order models for dispersed particle-laden flows; Large Eddy Simulations (LES) of reacting multiphase flows.
  • Surface wave measurements and analogies
    Experimental techniques for high-resolution visualization of shallow water waves; surface waves under the effect of asymmetric potentials; Nonlinear water waves; Visualization of shallow water waves in 3D printed models, analogies to electrodynamics.
  • Advanced Propulsion
    Theoretical analysis and computation of radiation pressure in Micro-electromechanical systems (MEMS); Asymmetric Vacuum Fluctuation Forces in nano-electronic devices.
  • Hydrodynamically-inspired Quantum Theory
    Classical hydrodynamic analogs of de Broglie waves, Ensemble interpretation, Realistic wave equations in quantum mechanics.
