Chapter 14. Principles of Unsteady-State Heat Transfer

14.0 Chapter Objectives

On completion of this chapter, a student should be able to:

  • Derive the equation for unsteady-state conduction with and without internal heat-generation

  • Calculate the Biot number (NBi), which compares the relative values of internal conduction resistance and surface convective resistance to heat transfer

  • Use the Biot number as a guide when choosing the appropriate solution method to solve unsteady state problems

  • Use the lumped capacity method to solve unsteady state problems where NBi < 0.1

  • Use equations to solve unsteady state problems with larger Biot numbers for a flat plat of thickness 2H or for a semi-infinite solid

  • Use convenient charts to help solve unsteady ...
