Various upwind approximate Riemann solvers have been tested on a bench of discontinuous test cases.
The efficacy of the new discrete operators is demonstrated using both smooth and discontinuous test cases.

In Example 2, a more severe discontinuous test function is given: r(t)=textstylebegin{cases} -t^{2},&tin [ 0,frac{1}{4} ), t^{2},&tin [ frac{1}{4},frac{1}{2} ]. end{cases}.
The application of the resulting SSC ENO method to a discontinuous test function shows a sharper resolution of the jumps and a higher order approximation of the percentiles near the singularity.
Thus, considering that the verification phase resembles an incremental discontinuous test, it could be suggested that V̇O2 data from verification phases are processed through 15- to 30-s time intervals, for example, although some authors advocate that 15 s averages are preferable [22, 31].
Numerical results obtained on smooth and discontinuous test problems of the Euler equations on unstructured meshes, highlight that the newly proposed extended bounds limiter exhibits superior performance in terms of accuracy and mesh sensitivity compared to the cell-based or vertex-based bounds implementations.
It is shown that the lifetime during discontinuous testing (166 h at 1000 °C hot dwell time) the system with Zr modified bondcoat outperformed the conventional system by a factor of four, while during cyclic temperature exposure (dwell time 2 h) only a minor lifetime improvement was found.
