abstract = "Turbulence models are an example of computer simulations that parameterize
complicated phenomena and depend on artificial model parameters heuristically justified from
empirical information and experimental data. To assess the confidence in the results of such a
turbulence simulation, a derivative-based sensitivity analysis is carried out. The sensitivities of
the flow over a backward-facing step with respect to parameters of the turbulence model are
investigated. The standard $k$-$\varepsilon$ model and the renormalization group (RNG)
$k$-$\varepsilon$ model are compared. Both turbulence models are implemented in the FLUENT code
to which automatic differentiation is applied using the ADIFOR system. In our case studies, none of
the two turbulence models turns out to be the least sensitive with respect to all turbulence
parameters.",
