Yet the position proved to be so unrobust that it was wilting under heat that was mild compared with the temperature that will be applied during the furnace heat of the election campaign proper.
The particle size reduction caused by oxidation during the furnace treatment was then measured as a function of furnace temperature.
The relative amount of oxide generated during the furnace tipping phase and the phase of metal discharge from the ingot wheel are then predicted.
The free surface modelling capability of SPH and 3D visualisation of the fluid flow leads to a better understanding of the flow characteristics during the furnace tipping phase of the operation.
In this paper the grid-free smoothed particle hydrodynamics (SPH) method has been used to predict the amount of oxide generated during a furnace tipping process, where the metal is poured into a launder.
The typical degradation mechanism of EB-PVD thermal barrier coatings (TBCs) that occurs during cyclic furnace testing of a commercial 7YSZ coating on a single-crystal nickel-base superalloy is analyzed.
The algorithm correctly measures (in contrast to the RMS surface roughness) an increasing surface undulation amplitude during initial furnace cycling, followed by a decrease in undulation amplitude near the end of the coating life as TGO spallation becomes prevalent.
Thus, the time temperature history identical to that measured at slab bottom during the furnace testing of Specimen HD12 (Lim and Wade 2002) is applied in analysis at slab bottom surface while the slab top surface has room temperature at the beginning of heating.
