https://doi.org/10.1007/978-3-642-96908-9 Overload corresponds to q* > 1, while operation at q* < 1 is called “partload”. The pump characteristics describe the behavior of head, power consumption and efficiency as functions of the flow rate (the behavior of NPSH=f(Q) is discussed in Chap. 6). The shape of these performance curves over the

Takehiko Ishiguro,Kunihiko Yamaji q* < 0.8, at high n. below q* < 0.9. Since blade inlet angles and channel cross sections are too large for the reduced flow rate, flow patterns during partload operation fundamentally change compared with the design point. The flow becomes highly 3-dimensional since it separates in the impeller and

Takehiko Ishiguro,Kunihiko Yamajilly drops to the vapor pressure of the liquid due to excess velocities, so that some fluid evaporates and a two-phase flow is created in a small domain of the flow field. The vapor condenses suddenly (“implodes”) as soon as it is transported downstream into zones where the static pressure again exce

Open System Architecture for CIM such as described in this chapter. The first design created that way is then subject to analysis and optimization by CFD. Even then the accuracy of performance prediction is not always satisfactory. This, because the 3D-flow through the pump depends on the complex shapes of the flow paths given by
