Paper presented at the 8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Mauritius, 11-13 July, 2011.
The paper presents investigation into the single water microjet
surface cooling producing a film of liquid water with phase
change. Tests were conducted under steady state conditions.
Theoretical model of surface cooling by evaporating microjet
impingement in the stagnation area is developed. Experiments
were conducted using nozzle size of 70 and 100μm. Results of
experiments were compared with predictions of the model
showing a good consistency.
