Previous studies have shown that the film cooling effectiveness can be improved by using a
winglet pair vortex generator upstream or downstream of the film hole, but these studies …

Film cooling is one of the most efficient and widely used cooling methods for high-
temperature components. The interaction between the film cooling jet and main flow creates …

In this paper, four kinds of film holes (cylindrical hole, fan-shaped hole, anti-vortex hole and
sister hole) are experimentally and numerically studied to investigate the effect of hole …

In order to investigate the flow and heat transfer characteristics of sister holes cooling
method, sister holes cooling structures have been applied on a flat plate with four primary to …

Kidney vortex is a typical flow structure formed by the interaction between jet and cross flow.
One case where kidney vortex is frequently observed and studied is film cooling: jet from a …

Experimental studies were carried out to study the effects of inclination angle (α= 20°, 30°,
40°) and blowing ratio (M= 0.5, 1.0, 1.5) on the vortex generator (VG) to enhance the film …

Three kinds of sister hole and one single cylindrical hole were experimentally studied in
order to analyze the effects of side hole position and blowing ratio on film cooling …

Modern gas turbines use combined internal and external cooling methods to achieve higher
cooling effectiveness. The internal cooling methods, like internal serpentine channel cooling …

Simulations and comparisons on the influence of internal coolant crossflow of a novel film
cooling hole design, called “sister holes”, and a baseline cylindrical hole were performed …

This study aims to investigate the cooling performance of various film cooling holes,
including combined hole, cylinder hole, conical hole, and fan-shaped hole. For film cooling …
