Pool Boiling Improvement Study of Different Structures and Geometries: A Review

Abstract

Over the last several decades, pool boiling heat transfer enhancement has increased by manufacturing various surfaces with different structures. This paper investigates these structured surfaces created using novel methods, such as wire electric discharge machining and microelectromechanical systems. These structures were developed for efficient boiling with the necessary surface architecture. The growth and behaviour of bubbles during boiling are affected by various factors such as temperature differences, surface properties, latent heat, and fluid properties such as surface tension. These parameters affect the pool boiling heat transfer conditions, such as heat flux, saturation pressure, and thermophysical properties of working water, which influence the heat transfer coefficient. Finally, the article summarizes the enhancement in pool boiling heat transfer and highlights the need for further research. Past experiences and identifying areas requiring more profound research are also discussed, pointing to future research and development.
