Energy conservation and management is the need of the present hour.Protrusions like Blocks, Partitions and Fins are considered as retarders during convection and consume more energy. This book deals the physics about laminar natural convection inside the ventilated enclosure with twin adiabatic blocks. A finite difference based two - dimensional Numerical analysis has been performed using Streamfunction - Vorticity approach.The twin solid blocks are initially placed across the flow path and then shifted away from the flow path.To make it interesting as well as comfortable for readers, the...
