Natural Convection Cooling of a Vacuum Flask

Application ID: 1448

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 flasks cooling power; that is, how much heat it loses per unit time. This example treats the natural convection cooling using two approaches:
• Using heat transfer coefficients to describe the thermal dissipation
• Modeling the buoyancy driven flow of air outside the flask to describe the convective cooling.

This model example illustrates applications of this type that would nominally be built using the following products:
