Journal of the Global Power and Propulsion Society, 2018 Five-hole-probes are common use in turbomachinery flow investigations, even though, inserting a probe into a flow field inevitably induces perturbations to the flow which can falsify the measurement results, especially when exposed to transonic flows ...

CFD Simulation of Transonic Flow Through the Tip-Section Turbine Blade Cascade Intended for the Long Turbine Blade [PDF]
MATEC Web of Conferences, 2022 The paper deals with numerical simulations of transonic flow through the turbine blade cascade consisting of flat profiles. The cascade is one of variants of the tip section of ultra-long blades, which were designed for the last stage of the steam ...

Investigation on Transonic Characteristics of Turbine Cascades.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1998 Transosic characteristics of three similar turbine cascades (designed for same condition, but with slightly different curvature of blade suction surface after throat) were tested by high-speed cascade wind tunnel. Experimental data showed small difference of curvature of blade suction surface after throat affected loss coefficient in transonic region ...

Aerodynamic Damping Characteristics of a Transonic Turbine Cascade [PDF]
Volume 4: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award; General, 1999 The unsteady aerodynamic characteristics of oscillating thin turbine blades were studied both experimentally and numerically to obtain the comprehensive knowledge on the aerodynamic damping of the blades operating in transonic flows. The experiment was carried out in a linear cascade tunnel by use of the influence coefficient method.

Pressure Bifurcation Phenomenon on Supersonic Blowing Trailing Edges
, 2018 Turbine blades operating in transonic-supersonic regime develop a complex shock wave system at the trailing edge, a phenomenon that leads to unfavorable pressure perturbations downstream and can interact with other turbine stages. Understanding the fluid
