✦ Synopsis

In this paper, we present a methodology for providing parametric uncertainty bounds on thermal fluid calculations. This methodology is based on a first order Taylor estimate for the flow field. The first derivative terms in the estimate are approximated by solving a linear partial differential equation known as the continuous sensitivity equation. Numerical results are provided which compare a CFD solution with published experimental measurements of a fluid with temperature dependent properties. The applicability of this formulation to boundary condition and geometric uncertainty is also discussed.
