Physical modelling

Physical model testing adds confidence to design

BHR Group has a large and dedicated test facility to study the flow behaviour through engineering structures. Plant design is optimised and performance verified to international standards by our team of specialist fluid engineers.

With 65 years experience in modelling of structures, systems and components, our multi-disciplined engineers and researchers are able to provide an integrated engineering approach to fluid system design and build, testing and verification, optimisation and scenario-planning. 

Scaled physical models cost little compared to overall scheme construction costs and the often expensive and timely consequential costs of failures. Undertaken early in the product cycle, physical model studies lead to greater hydraulic efficiency, improved safety and reliability and lower construction costs.  

Model tests are of value both for design purposes and as a convenient means of verifying specified performance. Undesirable flow phenomena can arise in complex or non-standard designs and physical modelling may be necessary to predict the effects with certainty. Using the appropriate tools and scaling laws, physical models can be used to measure and assess flow distribution, velocity and pressure variations, flow patterns, sediment deposition, scour and air entrainment.
