Numerical Analysis of Two-Phase Flow in Serrated Minichannels Using COMSOL Multiphysics
Journal Title: Journal of Industrial Intelligence - Year 2023, Vol 1, Issue 4
Abstract
In the realm of engineering, the significance of minichannels has escalated, especially in micro-scale multiphase fluid dynamics. This study conducts an extensive numerical analysis of two-phase flow in minichannels, utilizing the level-set method coupled with COMSOL Multiphysics®. Focusing on the minutiae of the liquid-gas interface, the research employs a two-dimensional grid to solve the incompressible Navier-Stokes equations, thereby illuminating the complex formation of diverse flow patterns in minichannels. A critical aspect of this investigation is the exploration of various geometric configurations at the inlet, particularly the examination of serrated air and water inlet channels. The findings reveal that serrated air inlets, when designed internally, effectively mitigate the buoyancy force across diverse channel configurations, ensuring stable and predictable flow patterns. Conversely, the configuration of water inlets plays a less significant role in controlling this force, underscoring the paramount importance of air inlet design in achieving optimal flow regulation. These insights not only deepen the understanding of minichannel flow dynamics but also provide practical knowledge for enhancing the efficiency of micro-scale systems. The implications of this study extend to the design of more effective minichannel applications, such as cooling systems, heat sinks, and heat exchangers used as evaporators. Moreover, the research highlights the necessity of considering geometric factors in minichannel flow analyses and sets the stage for future advancements in this evolving domain of engineering.
