Centrifugal Compressor Research. Research into centrifugal compressors (also known as radial compressors) has been a key part of the research into high-speed technology at LUT for the past two decades. In addition to published research papers, a number of licentiate theses and doctoral dissertations have been completed in connection with the research. Operating principal. A device that.

This paper presents the design of a centrifugal compressor for high-speed turbomachinery. The main focus of the research is to develop a centrifugal compressor with improved aerodynamic.
Abstract: In this paper a case study of a trans-sonic centrifugal compressor at various tip gap values is presented. At all clearance values, global parameters of efficiency and head coefficient were assessed for the rotor and the stage. All results were obtained through 3D CFD simulations carried out with the k-omega SST model. Results indicate that stage performance can easily be correlated.
Centrifugal compressors are used in a large number of different compression applications. This tutorial addresses applications for centrifugal compressors in the upstream and midstream sector, such as LNG compression, refrigeration, pipeline compression, compression for gas injection, gas lift, gas gathering, export compression, air compression, and others. The focus is on the specific.
Centrifugal compressors, in general, are used for higher-pressure ratios and lower-flow rates compared to lower-stage pressure ratios and higher-flow rates in axial compressors. Figure 6-3 is a map for centrifugal compressors that shows the effect of specific speed (N s) and specific diameter (D s) on their efficiency.The most efficient region for centrifugal compressor operation is in a.
All of these additional devices have important uses in the control of the centrifugal compressor. Centrifugal impeller. The key component that makes a compressor centrifugal is the centrifugal impeller, Figure 0.1, which contains a rotating set of vanes (or blades) that gradually raises the energy of the working gas. This is identical to an axial compressor with the exception that the gases.
A centrifugal compressor assembly in APU of full size is regarded as research object in this paper. Rotor presents tri-hub burst with 110% working speed. For a certain disk, the maximum translational kinetic energy of a single fragment occurs.
In this paper, a new technique for obtaining an axisymmetric centrifugal compressor characteristic is presented. This characteristic is built using the equations of mass, momentum and energy from first principles in order to provide a more complete model than those currently obtained via experimental data. This approach enables us to explain the resulting cubic-like shape of the characteristic.
An additive manufactured (AM) vaned diffuser for use in a centrifugal compressor research facility was designed and implemented. Utilizing an AM process to manufacture the diffuser reduces the long lead time that is associated with conventionally manufactured diffusers, and it increases the instrumentation capabilities within the flow path. Several AM techniques and a variety of plastic and.
A detailed description of a new centrifugal compressor surge test rig is presented. The objective of the design and development of the rig is to study the surge phenomenon in centrifugal compression systems and to investigate a novel method of surge control by active magnetic bearing servo actuation of the impeller axial tip clearance. In this paper, we focus on the design, initial setup, and.
The achievement of this research can effectively improve the regulation ability of IGV and the performance of compressor. Variable inlet guide vane (IGV) is used to control the mass flow and generate prewhirl in centrifugal compressors. The efficient operation of IGV is limited to the range of aerodynamic characteristics of their vane profiles. In order to find out the best vane profile for.

Stonewall or choke point for a centrifugal compressor occurs when the resistance to flow in the compressor discharge line drops significantly below the normal levels. Due to low resistance, compressor discharge sees very low back pressure. As suggested by the compressor maps for a fixed RPM value, compressor output increases as the backpressure at compressor discharge drops down. This leads to.This paper describes a method to estimate key aerodynamic parameters of single and multistage axial and centrifugal compressors. This mean-line compressor code COMDES provides the capability of sizing single and multistage compressors quickly during the conceptual design process. Based on the compressible fluid flow equations and the Euler equation, the code can estimate rotor inlet and exit.Figure 8 shows an example of the compressor’s load sharing control system by a master controller for the common header pressure. This alternate control system can be used instead of the above-mentioned system as shown in Figure 5.
