A numerical and experimental analysis is performed for natural convection heat transfer from
a horizontal cylinder enclosed in a rectangular cavity. The temperature distribution in the air
and the heat transfer coefficients are measured by a holographic interferometer and
compared with numerical predictions obtained by a finite-element procedure based on the
streamfunction-vorticity formulation of the momentum equations. The influence of the
Rayleigh number and the geometry of the cavity on the heat transfer are investigated.
