About AQFlow
|
||||||||||||||
| ASL AQFlow Inc., (a wholly-owned subsidiary of ASL Environmental Sciences Inc.), was formed in October 2000. AQFlow's mission is to produce acoustic scintillation flow measurement systems that will be globally recognized as the solution to the hydro-electric industry's toughest discharge measurement challenge: turbine flow measurement in short converging intakes of low-head plans.
ASL Environmental
Sciences has over 30 years of experience carrying out successful
flow velocity measurement programs in the most difficult ocean environments
from the Arctic to the tropics. The company has been working in hydroelectric
applications for over 20 years, since 2000 through AQFlow. Early projects related to the hydroelectric industry include:
In 2001, ASFM Advantage was released. It incorporated significant refinements, and has since been used successfully and effectively by:
In 2005, ASFM Monitor was introduced. This non-intrusive system can be installed permanently in the intake and provide continuous, repeatable and reliable real-time monitoring of turbine discharge. Typical Applications of the ASFM include:
Future Applications AQFlow
continues to pursue research into other challenging hydro applications
needing innovative flow measurement techniques, including spillways. Code Acceptance The process of
obtaining code recognition continues. It is expected that code acceptance
will be attained by the end of this decade. The international committees responsible for the ASME PTC-18 Hydraulic turbine and pump turbines and the IEC 41 Test code for field acceptance tests to determine the performance of hydraulic turbines are currently considering the inclusion of the acoustic scintillation technology in the next issue of their respective codes. CFD Modeling Computational Fluid Dynamics (CFD) modeling has been used by the industry to optimize hydro turbine designs for many years. CFD has now become an indispensable tool in the design of entire hydro installations, from intakes to draft tubes, and from forebays to tailraces. AQFlow has applied the CFD technique since 1998, using a cluster of computers and sophisticated CFD software including the latest ANSYS and Amtec products (CFX, Fluent, ICEMCFD). By conducting direct field measurements of velocity and turbulence in combination with the CFD modeling, AQFlow has gained better understanding of the complex fluid physics in the converging intakes of the low head plants. In turn, this helped us to make better measurements with the ASFM.
