... that the droplet-wall interaction is stronger on the pressure side than on the suction side, resulting in a higher mist cooling enhancement on the pressure side. The average rates of mist cooling enhancement of about 15% and 35% were achieved under laboratory and elevated conditions, respectively. This translates...

... of staggered impinging jets. The calibrated CFD model was then used to predict the mist cooling enhancement at the elevated gas turbine working condition. Using the experimental results, the CFD model has been tuned by employing different turbulence models, computational cells, and wall y + values. In addition...

.... The film cooling coverage could switch from the suction side to the pressure side and leave the surface of the other part unprotected by the cooling film. Under real gas turbine operating conditions at high temperature, pressure, and velocity, mist-cooling enhancement could reach up to 20% and provide...

... increases from 15 K to 45 K downstream of x / d = 15 – 30 in Fig. 6b . This is exactly what we really want because the downstream wall is hotter and needs more cooling. The prolonged effect of mist cooling provides this needed service. Heat transfer results of the 3D case...

... cooling technique is to inject a small amount of tiny water droplets (mist) into the cooling air to enhance the cooling performance. The key mechanism of mist cooling enhancement is attributed to the heat absorbed by evaporation of droplets when moving along the coolant air. The second cooling enhancement...

...-to-droplet heat transfer during impact releasing the latent heat of evaporation. Nirmalan et al. 12 conducted an experimental study of turbine vane heat transfer with water-air mist cooling. Water was pressured inside the vane and broken up into small droplets through many cooling holes on an inner...
