Heat Transfer from a Negatively Buoyant Wall Jet

摘要

An experimental investigation has been carried out on the heat transfer characteristics of a turbulent, negatively buoyant, two-dimensional wall jet. A jet of hot air is discharged adjacent to a water-cooled, isothermal surface in an extensive environment. The heat transfer to the surface from the elevated-temperature jet is measured along the isothermal surface for several values of wall, jet and ambient temperatures. Wide ranges of Grashof number, Gr and Reynolds number, Re, are investigated. The total heat transfer to the isothermal surface is obtained.
