Laminar two-phase boundary layers in natural convection film boiling of subcooled liquids

Analysis of residual strain and stress states due to heat treatment and thermal processing

“…The magnitude of the film boiling heat flux was found using the correlations of Frederking and Clark [46] and Frederking and Hopenfeld [47] Nu~0:15 Ra…”

A scale analysis model for film boiling heat transfer on a vertical flat plate with wide applicability

“…Starting from the pioneering work of Bromley [6] on film boiling, Dhir and Purohit [1], Zumbrunnen et al [3], Frederking and Hopenfeld [7], Shiotsu and Hama [8], Kolev [9], Jouhara and Axcell [10] and Meduri et al [11] carried out extensive experimental and numerical analyses. Some experiments [1,8,10,11] involved appropriate visualization studies and measurement of heat transfer during quenching of a surface from a high temperature.…”

“…The wall superheat and liquid subcooling were considered as the main parameters, along with other relevant thermo-physical properties of liquid and vapor phases. The theoretical analyses were based on either integral method [1,8,10] or similarity transformations [3,7] with two-phase boundary layer approximations over plate, cylinder or spherical geometries. The analyses considered the role of nondimensional numbers, representative of both superheated vapor and subcooled liquid layers.…”

Forced convection film boiling heat transfer model for a sphere by scaling analysis

“…A considerable amount of research was carried out to understand the heat and mass transport phenomena involving phase change during film boiling for different geometries. Starting from the pioneering work of Bromley [4], Dhir and Purohit [3], Frederking and Hopenfeld [5], Shiotsu and Hama [6], Kolev [7], Jouhara and Axcell [8] and Meduri et al [9] carried out extensive experimental investigation with visualization techniques and numerical analyses on film boiling. Theoretical investigation using integral method was performed by [3,6,7], whereas [1,5] incorporated similarity transformations.…”

Theoretical investigation using integral method was performed by [3,6,7], whereas [1,5] incorporated similarity transformations. Appropriate computational techniques were recently used [10][11][12] for direct numerical simulations to understand the complex flow pattern and bubble release mechanism.…”
