Ice Melting Blocks


 Model Description This demonstration illustrates the material property of thermal conductivity, and how this property affects conduction heat transfer in a solid.  Concepts include Fourier’s Law, conservation of energy and solid-liquid phase change.  This demonstration should take 8-10 minutes. Engineering Principle Fourier’s Law states that the heat transfer rate in a solid is proportional to […]

Parabolic Concentrator


 Model Description This demonstration illustrates how to concentrate radiant energy, solar or other, using a parabolic reflecting dish to produce high enough heat fluxes to burn paper.  This demonstration should take 10 minutes. Engineering Principle The sun is located far enough from the earth that radiation arrives here in nearly parallel beams.  A parabolic dish […]
