Summary
We present in a simple generic situation a new approach towards quantitative error control in computational fluid mechanics. Combining so-called strong stability and Galerkin orthogonality, we derive sharp a posteriori and a priori L 2 error estimates for stationary nearly parallel pipe flow governed by the incompressible Navier—Stokes equa-tions. These estimates state explicitely the dependence on the Reynolds number Re in the form of a multiplicative constant proportional to Re.
