Continuum Models and Singularities for Heat Distributions From Light

Abstract

Air flow and quasi-static heat around heat sources and shields are exemplified and analysed. The purpose is to (improve thermal efficiency, i.e.,) obtain much heat adjacent to the device and its surrounding. Knowledge from single devices and sources in a row is used and interpreted into comparisons with e.g. heat waves. Navier-Stokes equations, other balance equations, and rules from continuum mechanics are scrutinized and combined with proposals for the buoyancy of heated air. Results for singularities are derived and visualised with the aim to describe heat power potentials in room layers.
