where [C.sub.p,v] is the specific heat of steam (J/kgK), [DELTA][H.sub.wv] is the specific heat of vaporization (J/kg), and [N.sub.scf] is the electric energy of the feed screw (kWh/t).
Like polymer density, the correlation of the specific heat capacity at a constant pressure of the polymer melt changing with the polymer temperature [11] is as following:
where Q is the battery heat generation in J, m is cell mass in g, [C.sub.p] is the cell specific heat capacity in J/(g K), AT is cell temperature rise in K, q is battery instantaneous heat generation power in W, and dT/dt is temperature rise rate in K/s.
where T is the temperature ([degrees]C), [tau] is the curing age (d), [rho] is the density of concrete (kg/[m.sup.3]), [lambda]([alpha]) is the thermal conductivity at the different hydration degree (kJ/(m-d-[degrees]C)), c([alpha]) is the specific heat at the different hydration degree (kJ/(kg-[degrees]C)), and Q([alpha]) is the released heat associated with an internal source and is provided by the hydration reaction itself (kJ/([m.sup.3] x d)).
The behaviors of the rescaled specific heat [mathematical expression not reproducible] for the cases P < [P.sub.c], P = [P.sub.c], and P > [P.sub.c] are shown in Figure 1.
