This paper presents the results of a numerical study of unsteady natural convection
heat transfer from a pair of isothermally heated horizontal cylinders in water. In conjunction
with the developed numerical model, a genetic algorithm is designed to search for the optimal
spacing between the two cylinders that maximizes their overall heat transfer. When the
cylinders are vertically aligned, the heat transfer effectiveness of the upper cylinder is affected
by buoyancy-induced fluid flow induced by the lower cylinder. The established and validated
CFD model is used to analyse spectral data of local Nusselt number and velocity. The
optimization procedure identifies the optimal spacing for Rayleigh numbers ranging from 1e+6
to 1e+7.
