A cooling flow bifurcation member is positioned in an outside radial flow passage of a generator between an end portion of a stator core and a stator flange. The flow bifurcation member includes a main body portion having a tapered surface that transforms a first flow having a first velocity passing into the outside radial flow passage into at least one other flow having another velocity. The at least one other flow is directed along at least one of an outer surface of the end portion of the stator core and the stator flange.
