Transient temperature distribution in an orthotropic metal bar
QuickField simulation example
A very long square iron rod at Ti=260°C is suddenly immersed in a coolant at T0=37.78°C.
Plane-parallel problem of heat transfer.
a = 2", b = 1"
Iron thermal conductivity λx = 34.6 W/K-m, λy = 6.24 W/K-m
Initial temperature Ti = 260°C;
Coolant temperature T0 = 37.8°C;
Convection coefficient α = 1363 W/K-m²;
Specific heat C = 38 J/kg·K, ρ = 6400 kg/m³.
Determine the temperature distribution in the slab after 3 seconds at the center, corner edge and face centers of the bar.
To set the non-zero initial temperature we have to solve an auxiliary steady state problem, whose solution is uniform distribution of the temperature T0
A time step of 0.1 sec is used.
