Re: suggestions to agitate stream flow?

Off the top, I recall that Professor Reynolds found that increasing a
dimensionless number later called the Reynold's number to several
thousand, caused water flowing in an open channel which was flowing
quietly (laminar flow) to become turbulent.
Take home message: if the stream is penned in a narrow channel, to
flow faster, it will be agitated.
