Abstract
The uncertainty propagation and transient heat transfer from an extended surface are studied. The stochastic Biot number, the fin number and initial and convection boundary conditions define the uncertainty propagation for the temperature distribution in the extended surface. The amplitude of the propagated uncertainty was observed to have a transient evolution. The uncertainty may increase or decrease depending on the stochastic input parameters. Results are presented for the variation of temperature and heat flux due to uncertainties in the initial condition and conditions at the boundaries where heat is rejected.
