Abstract
Natural convective heat transfer from relatively short isothermal cylinders that have a rectangular cross-sectional shape and an exposed top surface is considered. The cylinders are mounted on a plane adiabatic base. Attention is first given to a numerical study of the case where the cylinder is vertical and pointing upward. Numerical and experimental studies of the case where the cylinder is vertical but either pointing upward or pointing downward are then discussed and good agreement between the numerical and experimental results is shown to exist. In obtaining the numerical results, the possibility of transition to turbulence in the flow over the cylinder has been allowed for. The numerically determined heat transfer rates from the front and back surfaces, the side surfaces, and the top surface of the cylinder are compared with the heat transfer rate from the entire cylinder. Lastly, attention has been given to cylinders that are much wider than they are deep.
