DIFFERENTIAL DIAGNOSTICS OF GAS-TURBINE UNITSBY THEIR MAIN COMPONENTS
Известия высших учебных заведений: Нефть и газ, 2016 The dependences were obtained which enable to determine the values of the performance factors of gas- turbine units such as gas turbines and axial-flow compressors. The results of testing of the received relations applicability for practical calculations

Integer programming for optimal yaw control of wind farms [PDF]
Wind Energy ScienceIt is well-known that wakes caused by wind turbines within a wind farm negatively impact the power generation and mechanical load of downstream turbines. This is already partially considered in the farm layout.

Improving The Performance Of Gas Turbine Power Plant By Modified Axial Turbine
, 2018 Computer-based optimization techniques can be employed to improve the efficiency of energy conversions processes, including reducing the aerodynamic loss in a thermal power plant turbomachine. In this paper, towards mitigating secondary flow losses, a design optimization workflow is implemented for the casing geometry of a 1.5 stage axial flow turbine ...

DOUBLE-REGULATED VERTICAL AXIAL WATER TURBINE
Journal of Energy TechnologyA double-regulated vertical axial water turbine, known as a Saxo turbine, has become a very well-recognised product of the company Litostroj Power, with over 30 commissioned units in the North American market over the previous decade. While this turbine became popular in the North American market due to its compact design, simplified civil construction

Variable turbine geometry for an automotive turbocharger with a small axial turbine
Proceedings of Global Power & Propulsion SocietyThe paper examines the implementation of a variable turbine geometry (VTG) and the reduction of its tip leakage losses in a small axial turbine turbocharger for charging lean-burn internal combustion engines. Due to the small turbine size, a reduction in the number of vanes and a redesign was required to match the design point of the non-adjustable ...
