Table 4-4<br />

Conservation <strong>of</strong> Energy Equation <strong>for</strong> the Atmosphere in Cell i (Continued)<br />

hj = specific enthalpy in cell j;<br />

qout = ~ W,j e,, hi , where the ij sum includes only gas flow paths and the<br />

..<br />

suflpression pool vent;<br />

%b. = heating rate from diffusion flame burning and bulk spontaneous<br />

recombination, see Sections 9.2 and 9.3;<br />

qboil = energy transfer rate from pool boiling calculated by the implicit solver, see<br />

Wboilin Table 4-3;<br />

qpa = energy transfer from submerged gas inflows, see Section 4.4.7;<br />

qgs = energy dissipation rate from work done by gravity <strong>for</strong> implicit processes<br />

= ~ ‘wJ,eJ,(HJ-H,)+g(w,o,l+ w~,)(H~,-H,)<br />

ji<br />

g = acceleration due to gravity;<br />

Hi = gas center <strong>of</strong> elevation in i;<br />

Hp,i = pool surface elevation in i;<br />

qex,so = energy transfer rate into the atmosphere from explicit processes<br />

= qbn,so+ %d.o + %C,boil + %-Q + %RV,g + %<br />

qbn,so = heating rate from deflagrations, see Wbn@above and qCb~above<br />

<strong>for</strong> other burning modes that are implicitly interfaced;<br />

%d,so = energy addition rate corresponding to user-defined mass<br />

addition rates, see Wud,,o;<br />

%C,boil = energy transfer rate from pool boiling calculated in the lower<br />

ceil, see w~,~ll;<br />

%-c,g = energy transfer rate from gases generated from CCI, see Wm,~;<br />

%RV,g = energy transfer rate from SRV or sparger sources, see WsRv,~;<br />
