Input parameter uncertainty analysis. Results of the average input parameter uncertainty (${\overline{u}}_{\text{input}}$) analysis. $X_i$ represents the corresponding input parameters to the CFD simulations, with $u_{\mathit{X}\mathit{i}}$ representing their systematic uncertainties obtained from the experiments. The nominal values of the parameters were taken from Table 1. The scaled sensitivity coefficients (${\widehat{X}}_i(\partial S/\partial X_i)$) calculated for each input parameter is also shows, which was fed into Eq. (16) to calculate $u_{\text{input}}$.
