BUBBLE ENERGY AND LATENT HEAT FLUX ESTIMATION

Краткое описание

This paper investigates the latent heat flux during saturated pool boiling. The local latent heat flux is considered on a single nucleation site and has a decreasing trend if the empirical relation between the bubble departure diameter and the departure frequency has an exponent on the bubble diameter equal to or larger than one. If the exponent is smaller than one, the local latent heat flux starts to increase with increasing bubble departure radius. Empirical relations between the bubble departure diameter and frequency, which enable the local latent heat flux to decrease with increasing bubble radius, were proposed. But some researchers of empirical relations suggest, and we take it to be possible, that this trend could also have an opposite nature. Besides this, an equation for estimation of the of latent heat flux was proposed to be used in experimental observations of boiling process.
