Numerical Study on Natural Convection Inside Quadratic Enclosure with Uniform or Non-uniform Heating from Below

Saddam Hossain Mullick, Sourav Majumdar, Debabrata DasGupta and Pranab Kumar Kundu

Abstract

Predicting thermal flow behaviors inside a quadrantal enclosure is the foremost impartial of the study with the non-uniform and uniform profiles of heat transfer through the bottom wall where the upright wall is sustained at comparatively low temperature and the curved wall is shielded. For understanding the buoyancy driven thermal flow behavior, vortex patterns, isotherms and Nu along the conduction wall are obtained under various Raleigh numbers (104 ≤ Ra ≥ 106 ). In this work, sinusoidal and constant temperature profiles have been applied from below. As Ra amplifies, the intensity of the buoyancy inside the enclosure rises, which results in an enhanced heat transit rate. Multiple circulations are found to form at high Ra in case of non-uniform bottom wall heating.
