Summary

A numerical study of natural and forced convection inside an auditorium of the National University of Mexico was performed. Two-dimensional steady-state simulations of the heat transfer and fluid flow processes within a cross-section of the auditorium were carried out using a computational fluid dynamics program. The boundary conditions were varied to obtain Rayleigh numbers in the range of 1,000 to 1.85 x 10 billions for natural convection and Reynolds numbers of 1,000 to 100,000 for the forced convection flows. The turbulence energy-rate of dissipation of turbulence energy model of turbulence was employed to predict turbulent forced convection. The aim of the study was to determine the air flow patterns and temperature field and their effect on thermal comfort conditions inside the auditorium.
