Classification of the operating conditions of a Kaplan turbine according to its impact in the structural integrity of the runner; Clasificacion de las condiciones de operacion de una turbina Kaplan de acuerdo a su impacto en la integridad estructural del rodete

Abstract

Each one of the operating conditions of the turbine according to the impact they have in the structural integrity of the runner is evaluated. By means of CFD (Computational Fluid Dynamics) analysis the pressure that the working fluid exerts on the blade for the turbine operating conditions is obtained. The oscillating disturbances induced by the flow, the angular velocity of the runner and the cavitation effect have been considered. The value of maximum stress for each one of the operating conditions is related to its respective values of cavitation. With this information those operating conditions that induce the greater values of stress and represent greater wears away in the runner are determined. This way, it is possible to avoid the more severe operating conditions and if this is not possible, lineaments of redesign are established to obtain more favorable operating conditions for the runner.

Mediante analisis de CFD (Computacional Fluid Dynamics) se obtiene la presion que el fluido de trabajo ejerce sobre el alabe para las condiciones de operacion de la turbina. Se han considerado las perturbaciones oscilatorias inducidas por el flujo, la velocidad angular del rodete y el efecto de la cavitacion. Se relacionan los valores de esfuerzo maximo para cada una de las condiciones de operacion con sus respectivos valores de cavitacion. Con esta informacion se determinan aquellas condiciones de operacion que inducen los mayores valores de esfuerzo y representan mayor desgaste en el rodete. De esta manera, es posible evitar las condiciones de operacion mas severas, y si esto no es posible, se establecen lineamientos de rediseno para obtener condiciones de operacion mas favorables para el rodete.}
