ABSTRACT A review on the heat transfer characteristics of systems of multiple impinging air
jets is presented. The objective is to provide profound physical knowledge for the design of …

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 …

Impingement/effusion cooling systems have been studied extensively over the past few
decades to constantly improve cooling performance as the turbine inlet temperature of …

The effects of jet-to-jet pitch ratios in both streamwise and spanwise directions (xn/d and
yn/d, ranged from 2 to 5), jet-to-target spacing ratio (zn/d, ranged from 2 to 4) and jet array …

Impingement cooling effectiveness of gas turbine vanes and blades can be further increased
due to the manufacturing feasibility of integrally cast airfoils which can provide narrow …

Measurements of the local heat transfer distribution on smooth and roughened surfaces
under an array of angled impinging jets are presented. The test rig is designed to simulate …

MODERN gas turbine engines typically operate with inlet temperatures of 1800–2000 K,
which is far beyond the allowable metal temperature. Film cooling is extensively used to …

Array jet impingement cooling is a prevalent method for the thermal management of high-
pressure turbine guide vanes. Nevertheless, cooling efficiency is often compromised by the …

The heat transfer and flow structure characteristics of a film-cooled leading edge model with
sweeping and normal jets were numerically investigated using the conjugate heat transfer …

Impingement channels are often used in turbine blade cooling configurations. This paper
examines the heat transfer performance of a typical integrally cast impingement channel …
