THERMAL STRESSES IN A HOLLOW CYLINDER WITH CONVECTIVE BOUNDARY CONDITIONS ON THE INSIDE AND OUTSIDE SURFACES

摘要

Analytical solutions for thermal stresses (radial, tangential, and axial) in a hollow cylinder with uniform internal heat generation for the thermal boundary condition of convective heating on the inside surface and convective cooling on the outside surface are derived. The analysis assumes the ends of the cylinder to be clamped, the axial strain to be negligible, and the radial stresses on the inside and the outside surfaces to be zero. Results are presented to illustrate the effects of internal heat generation parameter Q, convective environment temperatures ratio θ*, Biot number for convection on the inside surface Bi_1, Biot number for convection on the outside surface Bi_2, and the radii ratio p on thermal stresses distribution in the cylinder. The analytical solutions should serve as benchmarks for validating the numerical codes for dealing with more complicated cases.
