Once it has been determined the inverse optimization is converging, the second phase of evaluation is to visually check the simulated cooling curve
The cooling curve
of hypermonotectic Cu-40 wt.% Pb alloy melt is shown in Figure 2.
The three-step cooling curve
of ternary hydrate salt solution with different viscosities can be obtained to observe the supercooling.
Figure 1 shows this same DSC cooling curve
for a PP.
[10-12] These ingots have been analyzed by finite element analysis for Time Vs Temperature study (cooling curve
) to find out the cooling rates at 24 locations of each ingot for three different pouring temperatures of 750[degrees]C, 780[degrees]C and 810[degrees]C.
Each instrument was heated to 100[degrees] C to obtain a heating curve and then cooled to -100[degrees]C to obtain a cooling curve
. Finally, instruments were heated again to 80[degrees]C.
The highest content of bainite was found in the specimens with the cooling curve
40W which has the fastest cooling rate as shown in (Fig.
In recent year, some of the scholars present various effective approaches that attempt to control the cooling rate and cooling curve
. Literature works [16-18] tryto use distribute model predictive control to design a supervisory controller regulating the temperature curve.
Figure 2 shows the cooling curve
as a function of time and the caption of the thermocouples used.
They are arranged in sections on heat transfer, modeling and simulation, distortion and residual stresses, property predictions, quenchants and quenching, gas quenching, hardenability, cooling curve
analysis methodologies, and dilatometric analysis, modeling quenching and tempering induced phase transformations in steels, predicting quench-hardness within the whole volume of axially symmetric workpieces of any shape, the gas-cooling of multiple short inline disks in flow along their axis, and the dilatometric analysis of aging in aluminum alloys.
For floor cooling the supply water temperature or the average value of the supply and return water temperature is also controlled according to the outside temperature (flux control according to a preset cooling curve
) with a limiter based on the dew-point temperature in a reference room.
A cooling curve
, shown in Figure 1, depicting this behavior can be obtained by plotting, on semi logarithmic axes, the fractional unaccomplished temperature difference versus time.
