  A shell and tube heat exchanger design with respect to the total heat
transfer rate and temperature profile has been invstigated by numerical
modelling. The HE comprises of a single tube and has been resolved by the two
equation models namely, the k epsilon and k omega. The low RMS residual levels
calculated showed that the convergence is better in the k omega. The
differences in the heat transfer rates noted are likely due to the low number
of iterations on the flow and heat transfer helps explain the selection of an
appropriate model i.e. k omega.
