Abstract:

Efficiency of the technical state of the compressor station basic components depends on the timely prediction of the appearance of damages. It is defined by the estimation of the technical state of the basic components during the compression process. It is known that the two-stage centrifugal compressors are commonly used in the Ukrainian compressor stations. So, application software and algorithm for the two-stage centrifugal compressor have been developed, what allows to define its technical state parameters, taking into account the construction features of the compressor volute.

The compressed air then enters the combustion chamber, where it mixes with fuel and undergoes ignition, producing high-energy exhaust gases.

Abstract:

The motivation to design a more efficient and compact aircraft engine leads to a continuous increase in overall pressure ratio and decrease in the stage number in compressors. Compared to the traditional multi-stage compressor, a single-stage ultra-high-pressure-ratio centrifugal compressor with a pressure ratio higher than 10.0 can significantly improve the engine’s power-to-weight ratio and fuel economy with a reduced structure complexity. Thus, it has great potential to be adopted in the compression system of advanced aero engines, such as turboshaft engines, in the future. However, the hig

Abstract:

Variable inlet guide vanes (VIGVs) can regulate pressure ratio and mass flow at constant rotational speed in centrifugal compressors as a result of inducing a controlled prewhirl in front of impellers. Radial inlets and VIGVs are typical upstream components in front of the first-stage impellers in many industrial centrifugal compressors. However, previous investigations on VIGVs in centrifugal compressors were mostly conducted under the condition of axial inlets, and this study aims to focus on the effects of radial inlet on the VIGVs performance of a centrifugal compressor stage.

Abstract:

The performance of centrifugal compressors can be seriously degraded by inlet flow distortions that result from an unsatisfactory inlet configuration. In this present work, the flow is numerically simulated and the flow details are analyzed and discussed in order to understand the performance behavior of the compressor exposed to different inlet configurations. In a previous work, complementary to this present work, experimental tests were carried out for the comparison of a centrifugal compressor stage performance with two different inlet configurations: one of which was a straight pipe with

Abstract:

Reciprocating compressors and centrifugal pumps are rotating machines used in industry, where fault detection is crucial for avoiding unnecessary and costly downtime. A novel method for fault classification in reciprocating compressors and multi-stage centrifugal pumps is proposed. In the feature extraction stage, raw vibration signals are processed using multi-fractal detrended fluctuation analysis (MFDFA) to extract features indicative of different types of faults. Such MFDFA features enable the training of machine learning models for classifying faults. Several classical machine learning mo

Abstract:

The increasing demand for robust and high-performance centrifugal compressor stages has led to the development of several optimization and uncertainty quantification approaches. However, in the industrial scenario, geometric variations of such pre-engineered stages can occur during customer orders or non-conformity evaluations. In this regard, a rapid low-effort quantification of the impact of these changes has become critical for manufacturers. Against this backdrop, the present study provides an approach based on the joint use of computational fluid dynamics (CFDs) and artificial neural netw

The paper focuses on the optimal centrifugal compressor stage design and introduces a new approach to it that implies replacing a physical experiment with a numerical one. The efficiency of this approach is due to numerical testing of a large number of different variants of the compressor stage geometry for the same gas-dynamic parameters. Within the approach, for calculating and optimizing the compressor stage parameters, we developed a combined method not having the most empirical components. Relying on this method, we propose methods for calculating the parameters and optimizing the geometr
