Ventilation system with skewed rotor cooling ducts of 40-MW synchronous machine: a case study

This paper describes modified ventilation system and thermal analysis of low-power 40-MW turbo generator. The study compares thermal behaviour of the machine for three different arrangements of the rotor ventilation ducts. Variations of both the sub-slot and the radial ducts are analysed.&#x...

Model for torque estimation of pump system with horizontal pipe network

This paper investigates the possibility of torque estimation of Centrifugal Pump System (CPS) with horizontal pipe network topology. It illustrates the concept of a model-based scheme for hydraulic system simulation. The simulation model developed for CPS takes into consideration the hydraulic&#x...
