Research Abstract |
Seventy-six thermocouples were installed just below the surface of a heater block. First, estimation limit of surface heat flux was examined for the situation in which heat transfer region moves from center to the periphery. The inverse heat conduction problem was solved from temperatures at the thermocouples calculated. Second, surface heat flux was estimated from the measured temperatures by 76 thermocouples in the conditions where a single large bubble forms on the heat transfer surface. Heat flux of 0.4 MW/m2 or heat transfer 1kW/m per unit length of triple contact line was obtained.
