Research is carried out on

• Generation of renewable energy from rivers and the ocean

• Fundamental fluid mechanics and sediment transport

We approach these topics using field as well as small and large-scale experiments. Facilities include indoor and outdoor flumes, wave tanks and state of the art measurement technology (LDA, ADV, PIV.

Experimental data are used to refine theoretical and numerical models with the aim of providing effective solutions for engineering problems.

Main campus

At Highfield, we have two laboratories each of 110 m2. They contain

• a 0.3 m wide, 0.4 m deep and 12 m long tilting flume

• a 0.4 m wide, 0.4 m deep and 14 m long wave tank

• a 0.5 m wide, 1.2 m deep and 15 m long wave tank with absorbing wave paddle, and

• a general purpose flume of 1.5 m width, 0.6 m depth and 6 m length

Chilworth

At Chilworth Science Park, approx 8 km from the main Campus, we have an additional facility with • a 25 m long, 1.4 m wide and 0.6 m deep indoor tilting flume

• a 60 m long outdoor flume with a trapezoidal cross section of 2.1 m width at the base, and 0.5 m depth, max flow 0.8 m3 s-1

• A 60 m x 0.5 x 0.5 m prismatic channel, max flow 0.15 m3 s-1

Boldrewood Our new Hydromechanics building on the Boldrewood campus will house a range of large facilities designed for mixed mode teaching and research. The towing tank (138 m long x 6 m wide x 3.5 m deep) is equipped with a high-speed carriage and multi-element wave maker: it is the first new tank to be built in the UK for several decades, and the largest university-owned one.

A tilting sediment flume with a working section 0.6 m wide and 16 m long is being installed to complement the facilities at Chilworth. A second water tunnel will be constructed for higher speed flows.

An additional flume coupled with a wind tunnel will also be installed.
