Numerical Investigation for Entropy Generation of Natural Convection Flow and Heat Transfer inside a Prismatic Enclosure
This work examines the entropy generation and heat transfer in an air filled prismatic enclosure. This configuration has applications for heat transfer in domestic buildings with an aim to provide thermal comfort to the occupants in attic-shaped buildings as well as minimizing the energy costs associated with heating and air-conditioning.
Applications
•Cooling Electronic Devices •Solar Thermal Collectors •Controlling Fire •Nuclear reactors •Greenhouse •Measuring Air Movement •Heat exchangers
Numerical Procedure
Finite Element Method (FEM) is used with the help of COMSOL Multiphysics to solve the governing equations.
