Projekt je zaměřen na výzkum formování a chování vodovdušného proudu využívaného pro chlazení za vysokých teplot.

Description in English
Project goals are based on cooperation with US university (focusing on theory and experimental work in field of heat transfer) and US industrial partner (steel production). Result of the cooperation will be scientific theory about mist nozzles and mist spray cooling. Correlation between characteristics of mist spray (water-air ratio, flow rate, impact pressure) and cooling intensity will be created. Such correlation will enable to use results about mist nozzles in cooling applications in energy industry, mechanical engineering or metallurgy. The results will be published in journals as written in chapter 3.1.5. The results will be used to design new mist nozzle in final stage of the project.
