Pelton turbine jet flow investigations using laser Doppler velocimetry

What is it about?

Applying the non-intrusive technique of Laser Doppler Velocimetry (LDV) enables the analysis of high-speed Pelton turbine jet flow, as well as the assessment of secondary flow and turbulence fluctuations. LDV proves advantageous over Particle Image Velocimetry (PIV) in scenarios where the measurement application involves a high control volume of water flow as in hydraulic turbines models, making the introduction of a large quantity of neutrally buoyant seeding particles challenging. Unlike PIV, LDV is not dependent on seeding and possesses the capability to capture flow phenomena within any control volume of water flow. With superior spatial resolution in high-speed flows and more sensitivity to higher velocities, LDV's point measurement capability allows for a precise assessment of flow characteristics at specific point locations. Happy to share with you our latest paper, authored by me and Prof. Arun Kumar, titled as “Pelton Turbine Jet Flow Investigations using Laser Doppler Velocimetry.” is published in the Journal Physics of Fluids, American Institute of Physics Publishing and available at https://lnkd.in/gCf9Hs5f I am deeply grateful for the unwavering support and guidance of my PhD supervisors, Prof. Arun Kumar and Prof. Thomas Staubli.
