Example 1.6:transient conduction in one rectangular direction,x Let us assume that the body,0<x<L,has an initial temperature distribution as given byT=T(Tc-Ts).At time t=0 the skin temperature is changed suddenly to Tf.Ignore any energy generation. k OTT T=To(x)+X(x).t(t) Boundary condition:x=0 T=Te Ts x=L T=Tt Core Skin X(x)·T(t) Surface at x=0 and x=L X().r(t)=0 and dx at=0X侧r0=-i便.-T-ToWBoundary condition:
