Comparison of experimental and numerical data in 2D impact flow
Knob, Martin ; Antoš, Pavel ; Adamec, J.
In the contribution, the experimentally obtained and the numerically computed data in a two- dimensional impinging jet flow are compared. The calculations were performed using a commercial solver Fluent v. 6.1, while the experimental data were obtained using a hot- wire probe. In the calculations, both the k-SST and the RSM models of turbulence were employed. The comparison has been done for three various jet hydraulic diamater and jet mean velocity based Reynolds numbers, 2800, 8400 and 1400, respectively.
Influence of the non-linear resistivity-temperature relationship on the mean wire temperature
Antoš, Pavel
Hot-wire temperature is usually calculated by a linear resistivity-temperature relationship instead of much more accurate second order relationship. Effect of the non-linearity on the mean temperature is the subject of the paper.
