The tip leakage flow characteristics for flat and squealer turbine tip geometries are studied in
the von Karman Institute Isentropic Light Piston Compression Tube facility, CT-2, at different …

The primary focus of this paper is convective heat transfer in axial flow turbines. Research
activity involving heat transfer generally separates into two related areas: predictions and …

The flow around a low-pressure turbine rotor blade with incoming periodic wakes is
computed by means of DNS and LES. The latter adopts a dynamic sub-grid-scale model …

THE high complexity of turbomachinery ows, which are threedimensional, unsteady, and
often transitional, requires powerful computational tools and models. In recent years …

Unsteady component interaction represents a crucial topic in turbomachinery design and
analysis. Combustor/turbine interaction is one of the most widely studied topics both using …

In the past decade, pressure gain combustion research has promised over 10 percentage-
points of increase in power plant thermal efficiency. Alas, to realize such potential gain, one …

IN HIGHLY loaded turbine stages, the nozzle guide vane (NGV) exit flow is often transonic.
The design of efficient turbines thus requires a thorough understanding of the unsteady …

In this study, an analysis of steady-state and unsteady-state Conjugate Heat Transfer (CHT)
of an aeronautic high pressure gas turbine was conducted, which can calculate fluid and …

This article reports the measurements of time-resolved heat transfer rate and time-resolved
static pressure that have been made on the over-tip casing of a transonic axial-flow turbine …

This two-part paper presents detailed experimental investigations of unsteady aerodynamic
blade row interactions in the four-stage Low-Speed Research Compressor of Dresden. In …
