Abstract This text is a collection of solutions to a variety of heat conduction problems found in numerous publications, such as textbooks, handbooks, journals, reports, etc. Its purpose is to assemble these solutions into one source that can facilitate the search for a particular problem solution. Generally, it is intended to be a handbook on the subject of heat conduction. This material is useful for engineers, scientists, technologists, and designers of all disciplines, particularly those who design thermal systems or estimate temperatures and heat transfer rates in structures. More than 500 problem solutions and relevant data are tabulated for easy retrieval.
There are twelve sections of solutions which correspond with the class of problems found in each. Geometry, state, boundary conditions, and other categories are used to classify the problems.
A case number is assigned to each problem for cross-referencing, and also for future reference. Each problem is concisely described by geometry and condition statements, and many times a descriptive sketch is also included. At least one source reference is given so that the user can review the methods used to derive the solutions.
Problem solutions are given in the form of equations, graphs, and tables of data, all of which are also identified by problem case numbers and source references. Lawrence Livermore National Lab.

Each problem is concisely described by geometry and condition statements, and many times a descriptive sketch is also included. The introduction presents a synopsis on the theory, differential equations, and boundary conditions for conduction heat transfer. Some discussion is given on the use and interpretation of solutions.
Supplementary data such as mathematical functions, convection correlations, and thermal properties are included for aiding the user in computing numerical values from the solutions. 155 figs., 92 refs., 9 tabs. Nondimensional temperature distributions for transient radial heat conduction through hollow cylinders and onedimensional heat conduction in slabs of finite thickness are presented in graphical form for a range of heat input. The solutions are for radial heat conduction with heat transfer at the inner radius or slab heat conduction with heat transfer at one boundary.

In both types of conduction it is assumed that the boundary opposite the heat-transfer surface is thermally insulated. The radial solutions cover a range of dimensionless radius ratios. The material is assumed to be homogeneous, and the physical properties are considered invariant with temperature. This report documents the results of the verification effort recently completed for the general heat conduction code HEATING5. Objective was to verify HEATING5 for use in estimating the temperature distribution around a waste package after it is emplaced in a repository.
The approach taken in verifying HEATING5 was to compare the solutions obtained with HEATING5 to the analytical solutions for a series of problems for which analytical solutions existed. Ten analytical problems and one sample problem from the original source of HEATING5, the Radiation Shielding and Information Center, were chosen to verify HEATING5's capability to solve steady-state and transient heat conduction, including problems with an applied surface temperature or heat flux, constant or time-dependent thermal conductivity, and constant or time-dependent heat generation. This study did not attempt to verify HEATING5 for problems that involve convection, radiation, or anisotropic thermal properties. To support the analyses related to the conversion of the BR2 core from highly-enriched (HEU) to low-enriched (LEU) fuel, the thermal-hydraulics codes PLTEMP and RELAP-3D are used to evaluate the safety margins during steady-state operation (PLTEMP), as well as after a loss-of-flow, loss-of-pressure, or a loss of coolant event (RELAP). In the 1-D PLTEMP and RELAP simulations, conduction in the azimuthal and axial directions is not accounted. The very good thermal conductivity of the cladding and the fuel meat and significant temperature gradients in the lateral directions (axial and azimuthal directions) could lead to a heat flux distribution that is significantly different than the power distribution. To evaluate the significance of the lateral heat conduction, 3-D computational fluid dynamics (CFD) simulations, using the CFD code STAR-CD, were performed.
Safety margin calculations are typically performed for a hot stripe, i.e., an azimuthal region of the fuel plates/coolant channel containing the power peak. In a RELAP model, for example, a channel between two plates could be divided into a number of RELAP channels (stripes) in the azimuthal direction. In a PLTEMP model, the effect of azimuthal power peaking could be taken into account by using engineering factors. However, if the thermal mixing in the azimuthal direction of a coolant channel is significant, a stripping approach could be overly conservative by not taking into account this mixing. STAR-CD simulations were also performed to study the thermal mixing in the coolant. Section II of this document presents the results of the analyses of the lateral heat conduction and azimuthal thermal mixing in a coolant channel.
Finally, PLTEMP and RELAP simulations rely on the use of correlations to determine heat transfer coefficients. Previous analyses showed that the Dittus-Boelter correlation gives significantly more conservative (lower) predictions than the correlations of Sieder-Tate and Petukhov.
STAR-CD 3-D simulations were performed to compare heat transfer predictions from CFD and the correlations. Section III of this document presents the results of this analysis. Solution methods are developed to determine the temperature fields surrounding time dependent, cylindrical or spherical heat sources located in an infinite or semi-infinite medium. The method of superposition is employed to extend the single source solutions to the case of multiple heat sources. Numerical procedures are developed to efficiently evaluate the integral heat source solutions. Two computer programs based on the solution procedure are described. Complete user instructions and example problems for these programs are presented.
