Article
In this study, the cooling of a gas turbine (GT) blade leading edge using a single row of five impinging air jets was numerically and experimentally investigated. The inner surface of the blade leading edge was depicted as a semicircle profile. The numerical study was performed using a shear stress transport (SST) k-x turbulence model. On the other...

Computational study of cooling single wall mounted electronic component by jet impingement in cross flow configuration has been investigated. Five different turbulence models; standard k - ԑ, Realizable k - ԑ, RNG k - ԑ, Standard k–ω, and SST k–ω models were investigated. The results of flow structure as well as the local heat transfer coefficient...

Computational study of cooling semi-circular surface simulating the leading edge of gas turbine blade by row of impinging air jets. Five different turbulence models; standard k-ԑ, Realizable k-ԑ, RNG k-ԑ, Standard k-ω, and SST k-ω models were investigated and compared with experimental results obtained by using Infra-red thermal camera at the same...
Article
In this study, impingement/effusion cooling with cross-flow of in-line array of electronic components (ECs) is investigated numerically using RNG k-ɛ turbulence model. The cooling process is examined for two channel base configurations i.e., solid board (SB) and perforated board (PB). Effects of effusion perforation diameter (d/l) and its position...

Numerical study of the effect of jet position on cooling process of an array of heated obstacles simulating electronic components has been investigated based on Realizable k-ε model. Jet positions have been changed to impinge each row of obstacles consecutively. The experiments have been achieved at three different values of jet-to-channel Reynolds...

A computational study of cooling in-line array of heated obstacles simulating electronic components by jet impingement in cross-flow (JICF) has been investigated using RNG k-ε turbulence model. The jet position has been changed to impinge each obstacle consecutively at different jet-to-channel Reynolds number ratios, Rej/Rec = 1, 2, and 4. The main...
