Abstract
A water turbine with a rotatable turbine wheel having a wheel disc, buckets fixed to the wheel disc, and nozzle expelling a water jet on the bucket. The rotatable wheel and the nozzle are arranged in a casing with a water outlet. The interior of the casing reduces splash back of discharging water and detrimental water spray on the rotatable wheel. An energy damping device is attached on stationary, water splash exposed parts inside the turbine casing to dissipate energy from water of high velocity leaving the buckets and dense pulverized water mist.
