Hydrogen dispersion studies

Hydrogen dispersion and safety

Safety is not only a major consideration in achieving a hydrogen based renewable energy systems but also a crucial factor to dispel fear of hydrogen in society. Current research focuses on accidental leakages from compressed storage devices and also pipes when hydrogen is transported in a plant or in a filling station. We investigate safety scenarios by employing simplified but near-realistic geometries based on associated flow physics. The goal is to gain insight into the characteristics of a buoyant jet mixing with air. The numerical simulations are performed using the Large Eddy Simulation and experiments involve Particle Image Velocimetry (PIV) and Laser Induced Fluorescence for velocity and concentration measurements. The research also focuses on various scenarios involving cross winds and barriers to jet.
