Digital particle image thermometry/velocimetry (DPIT/V) is a relatively new methodology that
allows for measurements of simultaneous temperature and velocity within a two-dimensional …

The present review covers the heat transfer literature published in 2004 in English
language, including some translations of foreign language papers. Though extensive, some …

Film cooling on airfoils is a crucial cooling method as the gas turbine industry seeks higher
turbine inlet temperatures. Shaped film cooling holes are widely used in many designs given …

In modern gas turbine engines, the coolant is typically injected through the small cooling
holes on the surface of the blade using an internal crossflow. Most experimental and …

This paper presents a comparative-numerical investigation on film cooling from a row of
simple and compound-angle holes injected at 35° on a flat plate with four film cooling …

The implementation of spiral-channel holes has shown significant progress in heightening
the film effectiveness. However, the current investigation has certain limitations as it only …

A comprehensive evaluation of the cooling effectiveness of spiral-channel hole in turbine
vanes is carried out through a combination of cascade wind tunnel experiments and …

Numerical simulations are carried out to address further insights into the effects of round-to-
slot film cooling holes on a multi-row film-cooled turbine blade under representative engine …

This paper describes a multi-objective optimization method for round-to-slot shaped film-
holes (RTSH) using computational fluid dynamic analysis and surrogate model …

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 …
