Increasing the Operation Efficiency of Low Pressure Cylinders of Cogeneration Turbines

open access: yesNTU "KhPI" Bulletin: Power and heat engineering processes and equipment, 2017
An increase in the operation efficiency of cogeneration turbines used by big heat and power plants is conditioned by the need of a maximum use of the fuel heat, mainly that of natural gas. The generation of two types of energy, in particular electric and thermal by cogeneration turbines for outside consumers is closely related to turbine operation ...

Two dimensional analysis of low pressure flows in the annulus region between two concentric cylinders [PDF]

open access: yesSpringerPlus, 2016
A numerical simulation of the steady two-dimensional laminar natural convection heat transfer for the gaseous low-pressure flows in the annulus region between two concentric horizontal cylinders is carried out. This type of flow occurs in "evacuated" solar collectors and in the receivers of the solar parabolic trough collectors. A finite volume code is

On the discharge between concentric cylinders in gases at low pressures [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1912
In some previous communications the author has described investigations upon the length of the Crookes dark space and the relation between current and potential in the discharge between large plane aluminium electrodes in different gases at various pressures. For all the chemically active gases, and also for the gases of the helium group when these are

Estimation of unsteady aerodynamic forces using pointwise velocity data

open access: yes, 2016
A novel method to estimate unsteady aerodynamic force coefficients from pointwise velocity measurements is presented. The methodology is based on a resolvent-based reduced-order model which requires the mean flow to obtain physical flow structures and ...

Development of an optical time-resolved measurement system under high-pressure and low-temperature with a piston-cylinder pressure cell [PDF]

open access: yesReview of Scientific Instruments, 2016
To perform the femtosecond pump-probe spectroscopy under high pressure and low temperature, we constructed a measurement system with a piston cylinder type pressure cell installing an optical fiber bundle. The applied pressure was achieved to 6 kbar and the cell was cooled down to 15 K.
