Study of Natural Convection Heat Transfer in Different Shapes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 1
Abstract
This paper presents a review of studies on natural convection heat transfer in different shapes. In vertical tube a vertical copper tube having constant cross section area is used for representing the medium through which natural convection of water takes place. On two evenly heated vertically arranged horizontal cylinders with a diameter of 54mm in water. The change in nusselt number on the upper cylinder compared to a single cylinder is presented for seven Rayleigh numbers. Laminar boundary layer equations for natural convection from the outer surface of a vertical cylinder with a uniform temperature. Correlation for the local natural convection heat transfer from a vertical cylinder with the uniform surface temperature and the uniform heat flux.
