    The 180MW Francis turbine-generator running at full speed was instantaneously stopped by a foreign body left in the penstock following maintenance.[7] The installation shifted about 2m within the base of the 180m high earth and rock fill gravity dam wall of the 3,906GL reservoir.

    Francis inlet scroll at the Grand Coulee Dam Side-view cutaway of a vertical Francis turbine. Here water enters horizontally in a spiral-shaped pipe (spiral case) wrapped around the outside of the turbine's rotating runner and exits vertically down through the center of the turbine. The Francis turbine is a type of water turbine.

    The two engineers worked on improving the turbine. And in 1848, Francis and Boyden successfully improved the turbine with what is now known as the Francis turbine. Francis's turbine eclipsed the Boyden turbine in power by 90%. In 1855, Francis published these findings in the "Lowell Hydraulic Experiments". [8]

    The tangential water inflow of the mill race made the submerged horizontal wheel in the shaft turn like a true turbine. [1] A Francis turbine runner, rated at nearly one million hp (750 MW), being installed at the Grand Coulee Dam, United States. A propeller-type runner rated 28,000 hp (21 MW) The earliest known water turbines date to the Roman ...

    A November 2010, peer-reviewed article in International Water Power and Dam Construction suggested a previously unpublicized direct cause for the turbine failures: draft tube waterhammer. [20] The immediate cause of this is proposed to be simply the too-sudden closure of the turbine wicket (flow-control) gates.

    On 2 May 1990, the 180 MW Francis turbine-generator running at full speed was instantaneously stopped by a foreign body left in the penstock following maintenance. [7] The installation shifted about 2 m within the base of the 180-metre-high (590 ft) earth and rock fill gravity dam wall of the 3,906 GL reservoir.
