Crossflow water turbine is one of impulse water turbine type and can be also known as the Michell-Banki turbine. Michell-Banki is discoverer of this turbine type. Crossflow water turbine can be also called as Osberger turbine because of Osberger is company that manufactures Crossflow water turbine. Crossflow water turbine can be operated at discharge 20 liters/sec up to 10 m3/sec and head between 1 m up to 200 m.
Crossflow water turbines use rectangular nozzle which has width suitable the width of runner. Jets of water enter turbine and hit blades resulting in conversion of kinetic energy into mechanical energy. Water flows out hit the blade and provide energy (lower than at admission) and then leave the turbine. Runner turbine is made of several blades that are attached on a pair of parallel plate.
