2. Benchmark solution

2.1. Calculation method used for the reference solution

The reference solution is the one given in sheet TTLV01 /89 of guide VPCS.

• calculation of the coefficients,

• reading on the Gurney-Lurie abacus.

2.2. Benchmark results

Temperature on the surface and at the center of the sphere for \(t\) between \(400s\) and \(2400s\)

2.3. Uncertainty about the solution

< 2%

Below \(600s\), uncertainty increases (difficult to read the charts).
