NATURAL CONVECTION IN A VENTILATED DOUBLE GLASS WINDOW

Resumo

This study presents the numerical results of the flow problem induced by natural convection
in a channel between asymmetrically heated vertical parallel glass sheets of a ventilated double glass
window. The model is based on the equations of conservation of mass, energy and momentum in its
two-dimensional forms. The Finite Volume Method was used in the resolution with discretization
schemes of central differences for diffusive terms and Power Law for the convective terms. For the
coupling of pressure and velocity the SIMPLE algorithm is used, while the TDMA method is used in
the solution of the systems of equations. The numerical code is used to determine the velocity and
temperature fields between the glass sheets under real ambient conditions and asymmetric heating
conditions. The results were validated with available literature results indicating that the model is
adequate to solve this type of problem.
