Abstract :
This paper presents an analytical solution for two-dimensional conductive heat transfer in spherical composite pressure vessels. The vessels are in a spherical shape and fibers are winded in circumferential direction. The vessel is made of one-layer reinforced com-posite material. The analytical solution is obtained under the general boundary conditions which consist of convection, conduction and radiation inside/outside of vessel. The heat transfer equation for orthotropic conduction in spherical coordinates is derived and solved using separation of variables method based on the Legendre and Euler functions. Here, the effect of fiberʹs angle on heat conduction in orthotropic spherical pressure vessels is investigated in detail. These results can be used extensively for analyzing the thermal stress in this kind of vessels.
