• TITLE: Temperature Drop of Molten Metals in Open Channels

  AUTHORS: Miguel A. Barron-Meza, Joan Reyes-Miranda

  KEYWORDS: Free Surface, Heat Transfer, Molten Metal, Open Channel Geometry, Residence Time, Temperature Drop

  ABSTRACT: The temperature drop of molten metal flowing in open channels is numerically determined. Rectangular, trapezoidal and triangular geometries are considered. The overall heat transfer coefficients for the bottom, side walls and free surface of the channel have been taken from the literature. For each geometry, the volumetric flow rate, mean residence time and temperature drop as a function of the channel inclination angle were determined. The rectangular and trapezoidal geometries present the smallest temperature drops, while the triangular geometry presents the greatest temperature drop. The factors that most affect this drop are the value of the free surface area of the channel, and the average residence time of the molten metal in the channel.
