Hydraulic structures are designed to encounter and control the flow of water to meet a desired requirement. Examples include; water intakes, outfall structures, flood gates, spillways, artificial reefs and piers. Such structures are integral to the workings of large infrastructure projects such as bridges, dams and power plants. Therefore, detailed understanding of the hydrodynamic processes is essential if the overall design and operational control is to be efficient and cost-effective. In addition, the potential impact of the structures on the surrounding environment and ecology also requires attention.
Typical aspects of hydraulic structures which requires analyses includes the dispersion of heated water, siltation in intakes and pump systems, air entrainment, re-circulation of heated water, discharge optimisation, hydraulic loading and scour protection.
Our services are utilised from the conceptual phase to the optimisation of final designs and are based on hydraulic modelling combined with advanced simulation tools such as computational fluid dynamic (CFD) codes.
Within recent years CFD methods have been widely used as an engineering design tool for analysing of fluid dynamics. Some key benefits which CFD modelling provides are;
- The ability to virtually test engineering designs in a variety of scenarios.
- The data is not limited to a few measuring points, CFD allows for the extraction of key variables such as forces and velocities throughout the solution domain.
- The capability to model stratified flows.
Our ability to couple both physical model tests with numerical modelling allows us to utilise the strengths of both methods. This ensures that designs can be optimised and verified very efficiently.
