Formation of shock waves has high importance in study of supercritical flows. These waves are often found during supercritical flow in the non-prismatic channels. In the present study, values of depth and instantaneous velocity were measured in various points of shock waves observed in the straight-wall contraction for four Froude Numbers. Numerical simulation of supercritical flow in the contraction was performed using RNG k-ε and RSM turbulence models of FLUENT software. In order to investigate the accuracy of the models in calculation of wave profile and wave velocity a comparison was also done between the results of numerical models and measured values for Fr1=7.0. The average relative errors of the wave depth calculation using RNG k-ε and RSM turbulence models were 1.82% and 1.06%, respectively. Also, for the wave velocity, the values were 2.25% and 1.44%, respectively. The results showed that the RSM model performed slightly better than RNG k-ε model in simulating shock waves.
