This paper presents some results of experimental investigation on the free-convection heat transfer from a horizontal cylinder rotating to ambient air. The results have clarified that the travelling angle of the break away point can be expressed by an equation, [numerical formula] and the critical Reynolds number [numerical formula] in which G_r is the Grashof number. At Reynolds number below the critical one, the local heat transfer coefficient can be represented by an empirical equation [numerical formula] where ψ is the age from the break away point. The heat transfer data obtained by this experiment agree well with those by other investigators. Through the experiment the local heat transfer around the cylinder was ascertained by means of the Schlieren method.
