Dynamic Radiation Heat Transfer Control Through Geometric Manipulation, Rydge Blue Mulford Jun 2019

Dynamic Radiation Heat Transfer Control Through Geometric Manipulation, Rydge Blue Mulford

Theses and Dissertations

The surface area and radiative properties of an object influence the rate of radiative emission from the object's surface and the rate of radiative absorption into the surface. Control of these variables would allow for the radiative heat transfer behavior of the surface to be manipulated in real time. Origami tessellations, being a repeated pattern of linked, dynamic surfaces, provide a framework by which dynamic control of apparent radiative properties and surface area is possible. The panels within a tessellation form cavities whose aspect ratio varies as the device actuates. The cavity effect suggests that the apparent radiative properties of …
