Dynamique des fluides
Measure and visualize the movement of liquids, gases, and plasmas with high-speed imaging designed for flow, turbulence, sprays, droplets, shock waves, and complex multiphase behavior.
Making Complex Flow Visible
Fluid dynamics examines how liquids, gases, and plasmas move and interact with surrounding structures. Flow may be steady or unsteady, laminar or turbulent, compressible or incompressible.
High-speed imaging allows researchers to observe transient flow behavior, measure motion, and connect visible structures with pressure, temperature, velocity, force, and heat-transfer data.
Fluid Dynamics Applications
Photron cameras support fluid-mechanics research in automotive, aerospace, biotechnology, medicine, marine propulsion, electronics, and academic laboratories.
Liquid Flow
Study water, oils, chemicals, fuels, and biological fluids in channels, pipes, nozzles, pumps, and open-flow systems.
Gas & Aerodynamic Flow
Visualize air movement, jets, wakes, boundary layers, compressible flow, shock waves, and flow around structures.
Multiphase Flow
Capture bubbles, droplets, cavitation, boiling, condensation, particle transport, and interacting liquid-gas phases.
Sprays & Atomization
Analyze nozzle output, spray penetration, cone angle, ligament formation, breakup, and droplet distribution.
Droplets & Inkjet Printing
Observe pinch-off, oscillation, flight, impact, spreading, rebound, coalescence, viscosity, and surface-tension effects.
Microchannel Flow
Study confined single-phase and two-phase flow, boiling, cooling, heat transfer, and pressure-drop behavior.
Shock Waves
Capture supersonic flow, shock motion, underwater pressure waves, resonance, and rapidly changing density fields.
