RT Journal Article ID 6e27b37b79030179 A1 Weigand, Bernhard A1 Spring, Sebastian T1 Multiple Jet Impingement − A Review JF Heat Transfer Research JO HTR YR 2011 FD 2011-02-11 VO 42 IS 2 SP 101 OP 142 K1 jet impingement heat transfer K1 review K1 multiple jets K1 turbulent flow K1 experiments K1 CFD K1 correlation AB A review of the heat transfer characteristics of systems of multiple impinging air jets is presented. The objective is to provide a profound physical knowledge for the design of these impingement configurations, for which the factors that influence heat transfer are categorized and illustrated by exemplary results collated from different sources. In the course of the review, the flow and heat transfer characteristics of multiple impinging jets are introduced and compared to single impinging jets. Influencing factors on heat transfer are discussed, which include the effects of crossflow, jet Reynolds number, jet pattern, separation distance between a jet and target plate, and of the open area. An overview of the studies considering optimization and heat transfer enhancement is provided. In the review of numerical works, the suitability of the present CFD tools in predicting local heat transfer rates for multi-jet systems is discussed. Developments in the measurement technique and numerical accuracy are summarized. The review concludes with a summary and comparison of empirical correlations for both total average and locally resolved heat transfer coefficients.
