The present study employed commercial computational fluid dynamics software ANSYS
2019R3 to explore the adiabatic film cooling effectiveness and the net heat flux reduction …

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 …

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 …

Advances in cooling technologies have enabled turbine designers to push the turbine entry
temperature to temperatures as high as 1700° C which are well beyond the material limit of …

The full-scale CFD simulations may not be recommended in preliminary steps of STHEs'
design and sensitivity analyses because of heavy computations. This work benefits from the …

High fidelity big data obtained from highly accurate large eddy simulation (LES) was utilized
to enhance current models for turbulent heat transfer, boosting the precision of the realizable …

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 …

A numerical study was performed to evaluate the effectiveness of the novel sister hole film
cooling technique. Two secondary coolant holes bound the primary coolant hole slightly …

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 …

The present study evaluates a novel sister hole cooling technique using large inclination
angle cylindrical holes simulated numerically. Here, a 55° inclination angle has been …
