The comparison of experimental data with numerical predictions shows that while for the ruby laser a reasonable agreement in surface melt duration is achieved, the results for the ArF laser differ quite a lot.
To verify the model, its predictions for a laser pulse with a duration of ∼150 ns and a wavelength of 308 nm were compared to those of a phase-field implementation of melting laser annealing by La Magna et al. The two models show a good agreement for the melt depth, melt duration, and melt front dynamics.
The calculations of basic parameters of the processes such as surface melt duration, maximum reflectivity of the probe laser beam, etc., are verified using results of experimental work on GaSb samples irradiated by the ruby (694 nm, 35 ns FWHM) and ArF (193 nm, 13 ns FWHM) lasers.
This unit achieved a heating rate that was at least 10 times higher than those of conventional methods, as well as a far shorter melting duration.
Also, the thickness of the plates in the storage device plays an important role in the thermal performance of the unit and has a linear relation with the melting process duration of PCM for considered configuration.
When one or two of these parameters (melting temperature and duration) increase, the 'memory' of the hydrate previously formed fades: the subcoolings required for hydrate formation increase and are more scattered, i.e., they differ more from one drop to the other.
Longer durations of melting and higher interface temperatures enhance the flow of solder, improve wetting conditions and result in lower critical applied pressures.
The used model parameters of numerical simulations, and brief results, are shown in Tables 3 and 4, where is the time after CAI formation in Myr, tice is the duration of ice melting in Myr, tdehydration is the duration of the dehydration reaction in Myr, and Tpeak is the peak temperature at the center in kelvin.
The product design parameters explored were melting temperature and the duration of melting, API loading degree and the molecular weight (Mw) of PEO.
Comparing the results between Tables 3 and 4, we note that the initial temperature also affects the starting point and the duration of melting and dehydration reaction.
