Hydraulic Engineering Laboratory
The hydraulic lab is equipped with four major facilities: a Ferrocement wave flume, a long-stroke wave flume, a coastal wave-current basin and an oscillatory water tunnel. Laboratory instrumentation includes ADV (Acoustic Doppler Velocimeters), capacitance wave probes, ultrasonic wave probes, PIV (Particle Image Velocimetry) system, pressure sensor, load cells, high-speed cameras and bed profiler.
The research areas include Beach Morphology, Wave-Structure interaction, Sediment Transport, Wave-Current interaction, Flow over vegetation in open channels, Design/testing of offshore platform, and etc.
Oscillatory water tunnel
Dimension:Â 0.5m x 0.4m x10 m
Characteristics:Â The oscillatory water tunnel is a facility that can precisely produce controllable oscillatory flows or wave-current flows simulating the near seabed flows without scaling. The main part is a 10m-long test section with a 50cm-deep and 40cm-wide rectangular cross section. A 20cm trough of the test section is designed for holding sediments. Two 1m-diameter stainless steel vertical cylindrical risers are connected to the two ends of the test section through honeycomb flow filters. One riser contains a programmable, hydraulically actuated piston, manufactured by MTS, to generate prescribed oscillatory wave motions in the test channel, and the other is open to the atmosphere. The design limits for excursion, velocity, and acceleration of oscillatory flows in the test section are 2m, 2m/s, and 2m/s2, respectively, for periods 2s<T<12s. A Boerger EL1550 Rotary Lobe pump is connected to introduce currents of up to 60cm/s average velocity in the test channel. This facility can be used to study coastal sediment transport and flow-structure interaction (e.g. oscillatory flows over pipeline).
