Inner radius

\({R}_{i}=0.30m\)

Outside radius

\({R}_{e}=0.35m\)

Point \(F\)

\(r=0.32m\)

1.2. Material properties#

\(\lambda =1W/m°C\)

\(\rho {C}_{P}=\mathrm{2J}/{m}^{3}°C\) (volume heat)

1.3. Boundary conditions and loads#

  • \([\mathrm{DC}]\cup [\mathrm{AB}]:\)

\(\Phi =0W/{m}^{2}\)

  • \([\mathrm{EA}]:\)

\(T={T}_{i}=100°C\)

  • \([\mathrm{ED}]:\)

\(\Phi ={\Phi }_{i}=1729.9091W/{m}^{2}\) (incoming flow)

  • \([\mathrm{CD}]:\): exchange

\(h={h}_{e}=500W/{m}^{2}°C\)

\(T={T}_{e}=17.03444°C\)

1.4. Initial conditions#

To do this stationary calculation, a transient calculation is made for which the boundary conditions are constant over time. This makes it possible to test the elementary mass calculations taking place in the first member as well as the second member.
