Hydraulic Transients
Also known as “waterhammer” or “surge”, hydraulic transients have been the core of our business since it began in 1988. Since then, we have witnessed the evolution of the water and wastewater industry to more formally and comprehensively address the complex challenges associated with understanding and, more importantly, controlling and protecting against this phenomenon.
Having developed our own proprietary software, TransAM, based on decades of advanced scientific research and international project experienced, HydraTek is uniquely positioned as one of the few true independent experts in this field globally.
Below is a listing of typical services that we offer in this field of practice:
- Comprehensive hydraulic transient analysis and hydraulic modelling of fluid systems, including: water transmission and distribution systems, pressurized wastewater/sewerage systems, oil and gas pipelines, jet fuel supply systems, hydroelectric installations, and heating/cooling conveyance systems
- Surge protection design review, confirmation, and advisory services
- Pump station power failure, operational trip-up, and pipe break modelling
- Determination of safe pump ramp-up and ramp-down times
- Pump station operational risk assessments
- Analysis of full and partial valve closure scenarios
- Open channel and mixed flow hydraulic and transient modelling and analysis
- Hydrodynamic design of air valves for the purpose of minimizing secondary transients
- Inverse transient analysis and transient model calibration
- Turbine load rejection analysis
- Water column separation analysis in draft tubes, tail race tunnels and penstocks
- Short term and long term (permanent) transient pressure monitoring
