Impinging jets are often used in industrial applications for enhancing or damping localized heat transfer rates. When the flow is turbulent, thin boundary layers are located inside the stagnation zone, promoting even further cooling, heating or drying processes. Applications of such systems include metals cooling, glass tempering, electronics cooling, drying of textiles products and paper, to mention a few. In this book, two flow configurations are investigated, namely axisymmetric confined arrangements and two-dimensional planar jets. A fluid jet enters a cylindrical chamber through an aperture in an upper disk. An annular clearance between the cylinder lateral wall and the disc allows fluid to flow out of the enclosure.
