Our new wave-current channel is finally operational! We completed training and final commissioning of the facility early last week with a representative of HR Wallingford. Now we are just waiting for the surrounding renovations to be completed. Most mechanical work was completed last week and now they are fitting insulation and hanging drywall. The “flume room” and surrounding space should be finished out by the end of April. Until then, we are living in a construction area.

 

The channel’s capabilities are quite impressive. While it will likely take months to learn the nuances of our system, it is clearly capable of producing very clean waves.  The paddle’s active absorption system is really amazing and helps damp the reflected wave.

 

I have been somewhat hesitant to test the limits of the paddle, but that will surely change in the near future. The advisable limit for paddle acceleration is about 0.5G’s (4.9 m/s/s) and I think I have only tested up to about one-half of that suggested value.

 

So far I have experimented with the spectral, regular, and solitary-type waves. I was even able to generate a fairly steep wave that broke (spilling) off the paddle. The video below shows a low-amplitude (<10 cm), 2-s-period wave. Click on the triangle to play the video.

 

More updates coming soon, as well as an exciting announcement that may give  you the opportunity to come visit ‘South and see  our new facility first-hand!
