... cooling effectiveness contours on the bottom wall for the air-only versus the mist case at 0. 0.25 and 0.5 cycles Fig. 5 Validation of mist cooling simulation model showing a comparison of adiabatic film cooling effectiveness along the centerline of the experimental and the numerical results...

... scheme is investigated. A small amount of tiny water droplets with an average diameter of about 7 µm (mist) is injected into the cooling air to enhance the cooling performance. One key feature in understanding mist cooling is the ability to capture droplet information. In order to thoroughly investigate...

...: twang@uno.edu As discussed earlier in the Introduction, our research group has performed several experimental and numerical studies on steam/mist and air/mist cooling. The validation of the computational fluid dynamics (CFD) model in this study is conducted for the experimental study performed...
