Study of a Transformer Thermal System
... As the reads move away from the core, the temperature of the winding A rises, because the heat as more difficulty to flow due to the various isolation layers. As was already explained, the hottest temperature is verified in winding B, what it would be expected to happen as it is an internal winding ...

Dynamic Control of Radiative Surface Properties with Origami
... Various technologies have been investigated in order to vary surface radiative properties [8-10]. Specifically, the use of surface coatings and thin films [11], electrowetting [12] and electrostatic actuation [13] have been explored. Louvers have also been used for thermal control but macro versions ...

Effective conductivity of cell suspensions
... We used FEMs to calculate the effective (bulk) conductivity of cell suspensions. In Fig. 5, results for the normalized effective conductivity =e of the FEM model for the cells ordered into the sc, bcc, and fcc lattice are compared to the different analytical expressions. As stated before, the anal ...
