Vacuum Flask

Listing ID #3652626

The following example solves a pure conduction and a free-convection problem in which a vacuum flask holding hot coffee dissipates thermal energy. The main interest is to calculate the flask's cooling power; that is, how much heat it loses per unit time.Using heat transfer coefficients to describe the thermal dissipation, Modeling the buoyancy-driven flow of air outside the flask to describe the convective cooling.
