DynoRotor R&D & Testing

Low cost power and clean drinking water from slow moving water

 

History and ongoing Research and Development

 

1). From 2011 to present Waterotor Energy Technologies Inc  (our technology design partner and the company we are licensing the blade technology from) continues to perform Wind tunnel testing and real time analysis of the hydrodynamic features of the Waterotor / DynoRotor. 

 

Vigyan Inc. of, (Hampton, VA) has been doing Waterotor's wind tunnel testing since the beginning using NIST (National Institute of Standards and Technology) instruments and calibrations.  Vigyan, a NASA contractor, independently monitored and confirmed the proof of concept tests, having received test data via a direct feed. This independent analysis of the data confirmed the 30+% coefficient of power. Vigyan provides an extensive array of engineering support including wind tunnel testing, test engineering, computational fluid dynamics, and aerodynamic/hydrodynamic research. In addition to incorporating the NIST standards and adhering to ISO 9001:2008 protocols, Vigyan is a member of the Subsonic Aerodynamic Testing Association (SATA).

 

2). In 2014, 2015, 2016, many site demonstrations were completed on the 1kW sized DynoRotor / Waterotor in the St. Lawrence River at Cardinal Ontario at various water speeds. This test was linked in real-time to the Vigyan Laboratories at Langley, Research, VA. The following key technology features and capabilities were confirmed: three-blade configuration is most efficient; core drum to create added efficiency; optimal blade curvature, front and back, provides maximum power; a leading flow deflector (stator) to increase the capture area and accelerates water velocity.

 

3). in 2015, 2016, other tests were performed in Wakefield, Quebec, in various flow conditions which re-validated the coefficient of power, and electricity from this test ran several kinds of lights, electric bars, and an electric motor compressor. These test results have been confirmed in a series of tests in the summer and fall of 2014, 2015.

 

4). In spring of 2017, a small DynoRotor / Waterotor (100 watt sized unit) was constructed and tested in Southern Ontario.  All the videos created from these tests resulted in 61+ million Facebook & YouTube views.

 

5).  In August of 2017, a large (5kW) development unit (Black & McDonald produced) was tested for many weeks at the world’s largest Flume Tank at the Memorial University Marine Institute in St. John's, Newfoundland.  The unit configuration was representative of what will be per-production units; the actual Coefficients of Performance coincided almost exactly with predictions at various water speeds.  Data measurements were made for the largest unit using real-time power, water speed and RPM, all directly measured and recorded by a computer dedicated to this purpose.

 

6).  In November/17, February/18, the 1kW development DynoRotor was tested again in the Flume Tank at the Marine Institute.  Data measurements reinforced data from our previous tests.

Ongoing Testing of DynoRotor

In summer of 2019, DynoRotor / Waterotor started long term testing at the Canadian Hydrokinetic Turbine Test Centre (CHTTC), located on the Winnipeg River in Seven Sisters Falls, Manitoba. (CHTTC is a national centre focused on the testing of hydrokinetic turbines in Canada).

The CHTTC attracts turbine manufacturers and developers, including universities, and focuses on life-cycle project solutions for fully integrated systems. The center offers an actual commercial setting with the following assets: regulatory approval, equipment for manned and unmanned deployment and retrieval, a connection to the Manitoba Hydro utility grid using CSA standards for testing new power converters and test equipment to study the impact of the environment on turbines and the impact of the turbines on aquatic life.

The CHTTC provides an opportunity to better understand the operational effects of hydrokinetic devices on the environment and provides information to help inform regulatory decisions for future projects. The center provides significant cost savings to stakeholders by reducing the time and cost to market for developers and by providing a framework for the industry to develop standards, protocols and safety procedures. The CHTTC allows technology developers to save time, cost and effort when installing and field-testing their turbines.

 

The first product began long term testing on is our 1,000 watt (1kWatt) model.  This summer we will start testing our 500 watt model. It is DynoRotor's intention to continuously test ALL of our product models on an on-going basis before we release product for sale to the public.

 
The Marine Institute is home to the world’s largest flume tank.

 

Fisheries & Marine Institute of Memorial University of Newfoundland Canada. This facility is used to carry out performance evaluations, gear tests and other observations on newly developed or existing fishing gears and other related equipment in simulated underwater and near surface conditions. Constructed at a cost of $8.5 million CAD and first opened in 1988, the Marine Institute flume tank provides the physical environment required to:The key characteristic of a flume tank is its use of water as a working fluid circulated by large electric pumps situated in the downstream end.  Water speeds are typically varied between 0 and 1.0 m/s (0-2 knots), which at a scale of one-fifth for example, represents a maximum full-scale water speed of up to 4.5 knots.  Water is channeled using a series of diffusers, baffles, turning vanes, screens, and wave dampers before entering the test section.  Significant effort is made to reduce turbulence inside the test section in order to achieve uniformity of flow over the cross-section of the test section.

 

The test section is the centerpiece of the instrument where the fishing gear (or other test article) is deployed and observed on a model scale in a controlled environment. By reverse principles, models are not towed through the section, but remain stationary as the water and seabed move about them.  This permits the continuous and convenient visual observation of fishing gear in action. The effects of gear speed through the water are studied by controlling the speed of water flow, while the effects of gear speed over the seabed and boundary layer effects are studied by controlling the speed of a moving belt, which forms the bottom of the test section.  The belt moves in the same direction as the water flow and is synchronized to match the speed of water.  Models can be easily removed, modified, and redeployed, making the instrument particularly effective for demonstrating or investigating the effects of rigging changes on gear behavior and performance.
