ABSTRACT
For heat transfer in a semi-infinite slab, we can take the governing equation to be ∂ T ∂ τ = α ∂ 2 T ∂ x 2 $$ \frac{{\partial T}}{{\partial \tau }} = \alpha \frac{{\partial ^{2} T}}{{\partial x^{2} }} $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315108858/f4dff3a2-1feb-457b-a709-022257f02721/content/math22_1.tif"/>
