THE OPTIMUM OVERALL PRESSURE RATIO OF THE INTERCOOLED GAS TURBINE UNIT
Известия высших учебных заведений: Проблемы энергетики, 2017 In the article developed a mathematical model expansion and contraction of a real gas. Article shows the relationship between the isentropic efficiency of the compressor and the isentropic efficiency of the compressor stages. It was proved the need for a

Advanced Engineering Materials, EarlyView.Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.

Modeling Gas Compressor Station Operation to Minimize Fuel Costs for Surge Zone Protection
International Journal of Rotating MachineryGas transportation through the pipeline network requires high pressure; otherwise, movement will be impossible. Due to friction with the walls of the pipes, the gas loses both speed and pressure. Therefore, it is necessary to increase the pressure in the

Accommodating repair actions into gas turbine prognostics [PDF]
, 2013 Elements of gas turbine degradation, such as compressor fouling, are recoverable through maintenance actions like compressor washing. These actions increase the usable engine life and optimise the performance of the gas turbine.

Advanced Engineering Materials, EarlyView.This study investigates the fundamental mechanisms of a novel postweld treatment that significantly enhances fatigue performance through engineered residual stress (RS) states. A multiscale approach correlates tensile RS in the nanometallic multilayer coating with corresponding compressive RS in the steel substrate, thereby reducing localized stress ...
