NUCLEATE POOL BOILING HEAT TRANSFER OF ETHYL ALCOHOL FROM OSCILLATING SURFACE

The paper presents the experimental study of the ethyl-alcohol boiling heat transfer from the vertically and horizontally vibrating surface. It was recognized that the ethyl-alcohol is working fluid with the physical properties is adequate for the study of the effect of the change in the physical properties, in comparison with the water, for the analysis of the influence of the vibrating parameters on the boiling heat transfer. The experimental program of the boiling heat transfer investigation from the vertically and horizontally vibrating surface includes a following range of system parameters: heat flux - q = 9,8−53,5 W/cm2 ; liquids - ethyl-alcohol; pressure - atmospheric ; vibration frequency - f = 0−70 Hz ; vibration amplitude A = 0−2 mm.
