Marine Hydrodynamic Research Facility – The Hong Kong University of Science and Technology (Guangzhou)

The Marine Hydrodynamics Research Facility (MHRF) is a central research facility located at the Hong Kong University of Science and Technology (Guangzhou). It is jointly constructed and shared by the Hong Kong University of Science and Technology (Clear Water Bay) and the Hong Kong University of Science and Technology (Guangzhou), and is currently being incorporated into the Phase II construction of the Hong Kong University of Science and Technology (Guangzhou) campus. Once completed, it will become the only large-scale marine engineering laboratory in the Greater Bay Area.

The main experimental facilities of MHRF include the world's first combined deep and shallow water ocean engineering basin, O-Tube flume, a hydrodynamic flume, and a PIV flume. The O-Tube flume is 45m long with a cross-sectional dimension of 2m×2m, making it the largest oscillating flow flume in the world. The hydrodynamic flume is 85m long and 4m wide, with a water depth range of 0-2.2m, capable of generating simultaneous wind, wave, and current. The PIV flume is 30m long and 1m wide, with a water depth range of 0-0.8m, suitable for teaching and fundamental research.

The combined deep and shallow water ocean engineering basin at MHRF is 93m long and 45m wide, with the ability to generate wind, wave, and current. It is among the world's top-tier facilities of its kind. What sets this tank apart is that it combines a deep-water area with a depth of 10m and a shallow-water area with a depth of 2m in one basin, making it the first of its kind in the world. After installing a modular barrier structure in the middle of the basin, the deep-water area and shallow-water area can be used independently and are equipped with complete wind, wave, and current generation systems. The deep-water area is 57.6m long and 45m wide, with an adjustable floating floor. The shallow-water area is 45m long and 35m wide, with adjustable water levels.
