Abstract:

The paper envisages the results of calculation of a threedimensional viscous flow in 18 lowflow stages of centrifugal compressors in the range of optimal conditional flow coefficient Фopt = 0.007-0.018. Gasdynamic characteristics of the internal and polytropic pressure coefficients in full parameters were plotted and compared with experimental data. The calculated gasdynamic characteristics of viscous flow satisfying the engineering accuracy of calculations and experimental character of the curves were obtained using Ansys CFX software

Abstract:

This paper analyses effects of chemical reactions on reflected-shock flow fields in shock tubes. The method of linearized characteristics is applied to analyse gasdynamic disturbances due to chemical reactions. The analysis treats cases where combustible gas is highly diluted in inert gas, and assumes that flows are one-dimensional and that upstream flows in front of the reflected-shock waves are in the frozen state. The perturbed gasdynamic properties in the reflected-shock flow fields are shown to be expressible mainly in terms of a heat-release function for combustion process. In particular

Abstract:

In the framework of the research the authors have solved the problem of formation and dynamics of the vortex ring. Intensive turbulent vortex rings produced by piston generators have been considered. The research has been carried out on the basis of numerical simulations in fluid dynamics program ANSYS CFX using the high-performance computing system. We have obtained the dynamic and geometrical characteristics of the vortex ring on the basis of numerical experiments. The results are in agreement with self-similar law of vortex ring dynamics and experimental results. The authors have analyzed t

Abstract:

Current work covers experimental and theoretical investigation of conic confusers impact on the intensity shock wave, generated in the shock tube by explosion of gunpowder charge. For given conditions optimal geometric characteristics of the confuser, providing maximal pressure in the shock wave front, were found experimentally. The mathematical model was developed and numerical simulation of the axisymmetric shock-wave gas flow in the channel was carried out. Experimentally was shown, that the application of the optimal confuser provides significant increase of the efficiency gasdynamic effec

Abstract:

The matter of developing counter-rotating fans for advanced next generation aeroengines with ducted and unducted propfans is very important [1]. Counter-rotating fans can be made with fixed blades. This article considers tractor propfans consisting of two counter-rotating rotors of variable pitch (VPR) which valuable property is the possibility to turn their blades about the radial axis in order they can take the optimal position in direct thrust regimes, and to obtain a reverse thrust when turning them by a rather large angle. In this case there is no necessity to use a bulky special clamshel

Abstract:

Modern large capacity steam turbine for fossil power plants should have a high efficiency to be competitive in today’s tough market. It should be compact, with a smaller mass for reducing cost. In these circumstances, an effective solution is to create a large capacity steam turbine that consists of integrated high-intermediate-pressure turbine (HIPT) and one low-pressure turbine (LPT). Greater heat drop as compared to a conventional turbine shall be provided in LPT of such steam turbine. With this rather high efficiency of the low-pressure turbine should be provided.

When developing counter-rotating fans for advanced new-generation aeroengines with unducted blades it is very important to provide high acoustic and aerodynamic characteristics [1]. This paper presents some results of gasdynamic and aeroacoustic optimization of unducted CRF blade profile by using 3D viscous inverse problem. Flow in unducted CRF on the basis of unsteady 3D Navier-Stokes equations is modeled at the 1st stage of designing in order to find the key tonal noise sources. Based on these results, it is found that one of the key tonal noise sources is Rotor 1 - Rotor 2 tip vortices inte

Abstract:

One of the vital tasks related to the improvement of the efficiency of turbomachines is an increase in their operating altitude by reducing the influence of Reynolds numbers, Re, on the turbomachine parameters. Therefore, the results presented in this work on the effect of Re on parameters of an axial compressor composed of two high-loaded stages are attractive both from scientific and practical points of view. This work presents the results of experimental investigations of Re effect on gas-dynamic characteristics of a highly-loaded two-stage compressor (HPC-2), simulating the first two stage

The results of a new series of test ¦res of a detonation afterburner as part of turbojet engine are presented. In contrast to previous tests with a sequential arrangement of turbojet and afterburner [1], the new series provides for gasdynamic separation of air§ows: air is supplied to the afterburner separately using an auxiliary power unit simulating the bypass air§ow in a turbofan engine (Fig. 1). The separation of air§ows made it possible to ensure stable operation of the combined power plant in di¨erent modes of operation of the turbojet engine when the afterburner was turned on. In test ¦r

In [1], the innovative technology is proposed for pulsed detonation stamping of thin sheet parts. The technology consists in periodically exposing a workpiece to detonation waves and hot gaseous detonation products. The distinctive feature of the technology is the absence of a punch (the mating part of a pro¦led matrix). Compared to the detonation of condensed explosives, the use of gaseous detonation for stamping allows multiple periodic gasdynamic and thermal impact on a workpiece and simpli¦es the execution of technical supervision requirements.
