TLDR
In this article, the authors measured the local heat transfer distribution on smooth and roughened surfaces under an array of angled impinging jets, and determined the effect of jet angle, Reynolds number, gap, and surface roughness on heat transfer and pressure loss.Abstract:
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 impingement with crossflow in one direction. Jet angle is varied between 30, 60, and 90 deg as measured from the target surface, which is either smooth or randomly roughened. Liquid crystal video thermography is used to capture surface temperature data at five different jet Reynolds numbers ranging between 15,000 and 35,000. The effect of jet angle, Reynolds number, gap, and surface roughness on heat transfer and pressure loss is determined along with the various interactions among these parameters.read more

Streamwise Flow and Heat Transfer Distributions for Jet Array Impingement with Crossflow
TL;DR: In this article, two-dimensional arrays of circular jets of air impinging on a heat transfer surface parallel to the jet orifice plate are considered, and the air is constrained to exit in a single direction along the channel formed by the surface and the jet plate.
