Abstract
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.
Keywords: fluid dynamics, glacier modelling, glacier temperature, thermal
discharges.
1 Brief description of the method
In this paper some interesting applications of a method presented in Deponti et
al. [1] aimed at modelling meso-scale mass and energy flows in glaciers are
presented, together with applications of a similar method (Hagos et al. [2]),
modelling thermal discharges in water basins.
The method for the study of flow and thermal energy transport in water basins
is based on Navier-Stokes equation, coupled with the temperature transport
equation.
Keywords
fluid dynamics, glacier modelling, glacier temperature, thermal
discharges.
