Abstract In order to study the influence of the wrap angle relating to the space guide vane of a submersible well pump (250QJ125) on the flow field and pump performance, seven possible configurations have been considered (obtained by changing the blade wrap angle while keeping unchanged all the other parameters). Such configurations have been numerically simulated in the framework of a computational model based on the Reynolds time-averaged N-S equations, the RNG k-ε turbulence approach and the SIMPLE algorithm. The impact exerted by different wrap angles of the guide vane on the performance of the pump, the… More >
