During this process, the generated heat due to friction in between a rotor and brake pads interfaces is absorbed by the rotor and its nearby...

...Marios M. Fyrillas; Sayat Ospanov; Ulmeken Kaibaldiyeva In this paper, we consider the heat transfer problems associated with a periodic array of triangular, longitudinal, axisymmetric, and pin fins. The problems are modeled as a wall where the flat side is isothermal and the other side, which has...
