Query: Measurement and simulation of a temperature field   Measurements of surface temperature fields are used to determine the heat
transfer by conduction and convection from an inhomogeneously heated metallic
tube into environment. For most of the here reported measurements we use a
low-cost infra-red camera Seek Thermal, but the results are also compared to
measurements done with a professional Fluke Ti20 Thermal imager. The results
are interpreted using two simple theoretical models which give estimates of the
thermal conductivity of the tube and the heat transfer coefficient between the
tube and the environment.
