PD := [diff(Th(z, t), t) = 7.1428*(diff(Th(z, t), z))-1397941.885*(279-Tw(z, t))-0.2160487e-1*(diff(Th(z, t), z, z)), diff(Tc(z, t), t) = -7.1428*(diff(Tc(z, t), z))+1298990.852*(Tw(z, t)-291)+0.189366e-1*(diff(Tc(z, t), z, z)), diff(Tw(z, t), t) = 3.3024901*(Th(z, t)-2*Tw(z, t)+Tc(z, t))+8.0029*10^(-4)*(diff(Tw(z, t), z, z))]

BCI := {Tc(0, t) = 275, Tc(z, 0) = 275, Th(1, t) = 296, Th(z, 0) = 296, Tw(0, t) = 0, Tw(z, 0) = 0, (D[1](Tc))(1, t) = 0, (D[1](Th))(0, t) = 0, (D[1](Tw))(1, t) = 0}

pds := pdsolve(PD, BCI, numeric)
