Intro to Transient Thermal Analysis
courses.ansys.com•In the equation for transient heat conduction, the term on the right is the rate of energy storage in the body. We will call this the transient term. •This differentiates transient analysis from the steady-state, where temperature distribution does not change with time.

Transient Heat Conduction - Simon Fraser University
www.sfu.caTransient Heat Conduction In general, temperature of a body varies with time as well as position. Lumped System Analysis Interior temperatures of some bodies remain essentially uniform at all times during a heat transfer process. The temperature of such bodies are only a function of time, T = T(t). The
Conduction Heat transfer: Unsteady state - CHERIC
www.cheric.org6 Chapter Summary‐Transient Heat Conduction •No Internal Resistance, Lumped Parameter 1. The thermal resistance of the solid can be ignored if a Biot number is less than 0.1. 2. As thermal resistances are ignored, temperature is a function of time only. •
