Film Pool Boiling of Nitrogen from Flat Surfaces

Abstract

This paper presents the results of an experimental investigation of saturated film pool boiling from flat horizontal surfaces. Nitrogen at atmospheric pressure was used as the boiling fluid. Heat-transfer results were obtained over a range of temperature differences of approximately 1000°F (plate temperatures of 100 to 1100°F). The scope of the research has included correlation of data with analytical expressions relating heat flux, heat-transfer coefficients, fluid properties, and the temperature difference between the fluid temperature and the plate temperature for stable film boiling from flat horizontal surfaces in nitrogen. The experimental results and theoretical correlations for prediction of heat-transfer coefficients for film boiling are expected to have value in the design and analysis of nuclear reactors, space vehicles, quenching operations, and cryogenic systems.
