Temperature-dependent latent heat.
Constant gas temperature, no slip.
cpsol=1000, cpliq=2000 ,m=1.0
The particle temperature as a function of time within
the solidus-liquidus temperature range is given by:
(Cps.Tl+Cpl.Ts+DH0+2.Tg.(Cpl-Cps)).log((Tg-Tp)/(Tg-T0)) +
2(Cps-Cpl)(T0-Tp) = -alpha.DTLS.t/mass
where: alpha - particle heat transfer coefficient
Cpl - specific heat of liquid phase
Cps - specific heat of solid phase
DH0 - latent heat of solidification at Tp=0.0
DTLS - solidus-liquidus temperature range
mass - particle mass
t - time (time=0.0 when Tp=Tl)
Tg - continuous-phase temperature
Tl - liquidus temperature
Tp - particle temperature
Ts - solidus temperature
T0 - particle initial temperature
