“…Third, it has been compared to the experimental data of Zhang et al (1993) for the melting of octadecane (Pr = 53.5) in a discretely heated enclosure. The results of this validation are reported elsewhere (Binet and Lacroix, 1998). Finally, it has been validated with experimental data obtained in our laboratory.…”

“…The set of linearized equations is solved iteratively with a line-by-line tridiagonal matrix algorithm (TDMA) solver by sweeping the cavity from left to right. Further details on the numerical scheme are reported in Binet and Lacroix (1998) and need not be repeated here.…”

“…Again, except for the first few minutes of the transient, the agreement between the predictions and the data is within the experimental uncertainties. Further details on the validation of the present model are provided in Binet and Lacroix (1998) and Binet (1998).…”

“…A series of numerical simulations was conducted to determine the effect of the number of heat sources n, of their size and span and of the cavity aspect ratio A = H/W on the melting process. The effect of the wall thermal diffusivity has been reported in , Binet and Lacroix (1998) and and will not be discussed here.…”

“…Moreover, none of the available studies have examined the effects of the cavity dimensions and of the heat source distribution on the melting process. Recently, the authors have presented a computational methodology for predicting the melting process inside uniformly and discretely heated cavities (Binet and Lacroix, 1998). The effect of the source dimensions and span, of the cavity aspect ratio and of the wall-PCM thermal diffusivity ratio was highlighted.…”

A numerical study is conducted for natural convection dominated melting inside discretely heated rectangular enclosures. This study finds applications in the design and operation of thermal energy storage units and the cooling of electric equipment. Results show the benefits of discrete heating over uniform heating for optimizing the melting process. For enclosures of high aspect ratios (A ∼> 4), configurations leading to well controlled heat source temperatures and long melting times are obtained. For cavities of low aspect ratios (A ∼< 4), it is found that the source span η is the most influential parameter. For η ∼ < 0.45, the melting times are shorter and the heat source temperatures remain equal and moderate during the entire melting process. A map for determining the cavity size and the source distribution that optimizes the melting process is presented.
