| Description: | THIS WORK IS CONCERNED WITH THE TOPOLOGY OPTIMIZATION OF THE AREA BETWEEN THE TWO FRICTION SURFACES OF A BRAKE DISC, TARGETING THE SHORTENING OF THE COOL-DOWN PERIOD THAT FOLLOWS AFTER AN INTENSE HEAT-UP OF THE DISC. INITIALLY, FLOW AND CONJUGATE HEAT TRANSFER (CHT) PROBLEMS (WITH OR WITHOUT COOLING FINS) WILL BE STUDIED IN STEADY STATE, BY ADDING TUNED HEAT SOURCES IN THE CELLS LYING NEXT TO THE FRICTION SURFACES. THEN, STARTING FROM THE COMPUTED TEMPERATURE DISTRIBUTIONS, UNSTEADY RUNS WILL BE PERFORMED BY ELIMINATING THE HEAT SOURCES, SO AS TO COMPUTE COOLING CURVES W.R.T. TIME. STEADY-STATE TOPOLOGY OPTIMIZATION THAT WILL CHANGE THE SOLID MATERIAL DISTRIBUTION IN THE AREA BETWEEN THE TWO DISCS FOLLOWS. THE SOLUTIONS OF TOPOLOGY OPTIMIZATION WILL BE TRANSFORMED TO STL FILES, BODY-FITTED GRIDS WILL BE GENERATED AND, THEN, STEADY AND UNSTEADY SIMULATIONS WILL BE PERFORMED ON THAT, REPORTING THE SAME COOLING CURVE. |
