- Title
Accurate temperature–time diagrams for simple bodies heated uniformly by heat fluxes: Calculations with symbolic algebra codes.

Campo, Antonio; Salazar, Abraham
- Abstract
The present study addressed the problem of unsteady heat conduction in simple bodies exposed to a uniform heat flux at the surface (Neumann boundary condition). The exact series solutions have been computed with a symbolic algebra code permitting the construction of accurate temperature–time diagrams for the surface, center, and mean temperatures of simple bodies. Also, these solutions have been supplemented with an approximate physical approach, the semi-infinite body solution, which is applicable to short times only. Maps of solutions indicating the blending of inner and outer solutions have been explored for each of the three configurations, e.g., slab, cylinder, and sphere. The influence of curvature effects is also discussed. © 1997 John Wiley & Sons, Inc. Comput Appl Eng Educ 5: 127–133, 1997
