An experimental setup has been designed to study a single cylindrical fin placed in a cylindrical enclosure filled with phase changing material (PCM). The heat flux to the fin is measured at the top of the fin. The temperature evolution at different fin heights is measured by thermocouples placed internally in the fin. The evolution of these temper...

Context 1
... study aims to give a first insight in the fin effectiveness by discussing the temperature evolution of the fin over its length at different heat fluxes. figure 1. The test section consists of four main sections: the enclosure filled with PCM, the heat transferring section, the additional support and sealing and finally the insulation. ...
Context 2
... can be used to fill the enclosure and can be opened to allow expansion of the PCM if needed. The heat transferring section adds heat to the enclosure and is indicated in orange/brown in figure 1. From top to bottom, it consists of a brass upper fin, the heat flux sensor and the stainless steel lower fin. ...
Context 3
... between the support plate and the top plate of the container 10mm ceramic fiber insulation is added to avoid heat losses through the top of the container. The whole setup shown in figure 1 is surrounded with 18cm of glass wool placed in a polyurethane (PUR)-box. ...
Context 4
... experimental uncertainty analysis showed that the accuracy of all temperature measurements is within ±0.20°C. The position of these thermocouples is indicated in figure 1. The thermocouples are positioned internally in the fin to not disturb the heat transfer at the fin-PCM-interface. ...
