Numerical study of the effect of jet position (JP) on cooling process of an array of heated obstacles simulating electronic components has been investigated based on realizable k–e model. Jet positions have been changed to impinge each row of obstacles consecu- tively. The experiments have been achieved at three different values of jet-to-channel Reynolds number ratio, Rej/Rec¼1, 2, and 4. ... إقراء المزيد

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-?? turbulence model. The jet position has been changed to impinge each obstacle consecutively at different jet-to-channel Reynolds number ratios, Re j/Re c =1, 2, and 4. The main flow structure, the static pressure, local and ... إقراء المزيد
