Abstract:
Design and development of experimental apparatus is detailed for stator drag torque measurement as well as a method to evaluate rotor windage losses directly from air mass flow and temperature changes. Effects of air jets at the rotor rim were also investigated. Results are presented for air windage losses associated with ultra-high-speed machinery. These show that within the range investigated the air gap length between the rotor and the stator has an insignificant effect on windage losses. The lowest windage losses were encountered when air was forced through the rotor/stator gap from the di

Abstract:
The results of experimental performance tests on a 99.0 mm radial inflow turbine with seven different nozzle throat areas were reported by the same authors in a previous publication (1). In order to perform a loss analysis, dividing the turbine losses between the stator and the rotor, a theoretical model of the stator loss was required. Several stator loss models were evaluated and the model described by Rohlik (9) was used as the basis for a loss analysis. Plots are given for the breakdown of losses at two operating speeds for each nozzle size. Both the stator and the rotor losses decreased m

Abstract:
The topic of this paper is the determination of rotor harmonic losses in multiphase machines. Specifically, harmonic losses occur in the rotor winding and core due to higher-order spatial harmonics of the flux density. This phenomenon influences machine parameters and overall performance and increases temperature rise in parts of the rotor. The flux density distribution is determined by the stator magnetomotive force harmonic content, which is directly related to the winding distribution. A cage-rotor asymmetrical six-phase induction machine is selected for this case study. An analysis of diff

Abstract:
Eddy current losses in magnets are a major consideration in the rotor design of permanent magnet synchronous motors (PMSMs). Stator design choices and the use of modern inverters with high switching frequency introduce harmonics that can contribute to significant losses in the magnets, causing the rotor to heat up. In typical PMSMs, the lack of rotor cooling can cause the magnet’s performance to degrade at high temperatures and eventually demagnetize. This review examines a large number of studies analyzing magnet eddy current losses using analytical methods and finite-element analysis. In som

Abstract:
On the basis of the known fact that all air gap main flux density variations are enclosed by permeance slot harmonics, only one component of stray losses in rotor (stator) iron is considered in the new classification, instead of 2 components: rotor (stator) pulsation iron losses, and rotor (stator) surface iron losses. No-load rotor cage (high-frequency) stray losses are usually calculated. No-load stray losses are caused by the existence of space harmonics: the air-gap slot permeance harmonics and the harmonics produced by no-load MMF harmonics.

Abstract:
Different from the design of conventional permanent magnet (PM) motors, high-speed motors are primarily limited by rotor unbalanced radial forces, rotor power losses, and rotor mechanical strength. This paper aimed to propose a suitable PM motor with consideration of these design issues. First, the rotor radial force is minimized based on the selection of stator tooth numbers and windings. By designing a stator with even slots, the rotor radial force can be canceled, leading to better rotor strength at high speed. Second, rotor power losses proportional to rotor frequency are increased as moto

An extensive performance investigation has been conducted on a radial turbine with three different vaneless volutes and three corresponding vaned stators.

The volutes and the vaned stators were all machined in order to achieve high quality and comparable surface finishes. At all operating co

An industrial rotor-stator mixer was fitted into a flow loop to carry out overall power balance, flow visualisation and residence time distribution experiments.

Two different air gaps were tested.

In order to achieve high aerodynamic efficiency of a turbine stage, it is crucial to identify the source of aerodynamic losses and understand the associated loss generation mechanisms. This helps a turbine designer to maximize the performance of the turbine stage. It is well known that aerodynamic losses include profile, endwall, cooling/mixing loss, leakage, and trailing edge loss components. However, it is not a trivial task to separate one from the others because different loss sources occur concurrently and they interact with each other in a machine.

Abstract:
Abstract Modern high-performance multistage axial compressors are designed for high aerodynamic loading and efficiency, wide range and operate front stages with rotor inlet relative Mach number above one over a large portion of span. Understanding unsteady flow phenomena and rotor-stator interactions is paramount in the design of front stages. With increased aerodynamic loading, rotor shock waves may propagate upstream and interact with stator vanes. Such interaction may affect both performance and aeromechanics as shock propagation and reflection may destabilize boundary layers leading to hig

Abstract:
A nonlinear harmonic methodology is adopted to analyse interactions between adjacent stages in multi-stage compressors. Of particular interest are the effects of circumferential ‘aperiodic’ distributions and the relative circumferential positioning (‘clocking’) of blades. The main feature of the present approach is that both the aperiodic and clocking effects are very efficiently included with circumferential ‘steady’ harmonic disturbances. Consequently, a single run of the nonlinear harmonic solver using a single-passage domain can produce the whole annulus unsteady and aperiodic time-average
