According to recent research from the United States, "Experiments are conducted to investigate nucleate boiling of HFE-7100 liquid on 10 x 10 mm copper surfaces with corner pins that are 3 x 3 mm in cross section and 2-, 3-, and 5-mm tall. Heat transfer coefficient and critical heat flux are compared for 0 (saturation), 10, 20, and 30 K subcooling at orientations from theta = 0 to 180 deg."
"Thermal power removed in nucleate boiling at all orientations increases, partially due to the increase in surface area for boiling and the increased mixing by departing bubbles from the plane portion of the surface and sides of the pins. Increasing subcooling and pin height ...
