How Warm is the Igloo
... The igloo was modeled as an axis-symmetric quarter circle. Our goal was to determine the temperature profile and air flow in the igloo at steady state. Our problem definition also involved modeling the air inside the igloo as incompressible for simplicity. The non-linear parameter was used in this p ...
