The dimensionless transient temperature

and average temperature

of a plate (

), cylinder (

), and sphere (

), described by the partial differential equation problem
∂ξ θ(ξ,τ),

,

,

, are plotted (transient in orange, average in blue) as a function of dimensionless time

. The numerical values for transient and average temperatures can be computed for any dimensionless coordinate

and time

.
