Emerson Cavitation Tunnel

Post from RICOH THETA. #theta360 - Spherical Image - RICOH THETA

A specialist flume for hydrodynamic research of propellers, turbines, foils, bluff bodies, coatings and innovations.  The test section is 3.1 metres long and has an adjustable working cross section of 1.2 x 0.8 metres. Atmospheric pressure within the tunnel can be adjusted to enable analysis and visualisation of cavitating flow. We keep an extensive range of instrumentation for the analysis of cavitation, propeller/turbine performance, underwater radiated noise, surface pressures, flow velocity (including LDA and PIV lasers), flow visualisation (including stereoscopic PIV and high-speed video), boundary layer formation and coating drag
