Description
Summary:Studying heat transfer in 3D water or ice basins involves the solution of Navier Stokes or Stokes systems of PDE, coupled with a scalar equation for thermal energy transport. The method used in this paper is based on a Finite Volume technique where physical quantities and boundary conditions are approximated by means of high order formulae and the time advance is dealt with by a fractional step technique. This paper is mainly concerned with applications, but, with respect to a preceding version of the method, an evaluation of performance of techniques dealing with the turbulent viscosity in water basins is presented and a study of the temperature field in a glacier is included. The method is applied to a thermal discharge in a water basin of lower temperature and to a portion of the Priestley Glacier (Antarctica). The results are very accurate and coherent with the physical theory and with measured data.
