Indirect measurement of temperature distribution and power flow using the finite element method

We present the principle of indirect measurement of temperature in heat-transfer problems. We apply the principle of indirect measurement of power flow and temperature distribution on the surface of the test limiter of the Tokamak at Varennes (TdeV) using the method of finite elements in 3-D. During a 200-kA tokamak discharge, the hemispherical head was submitted to a power of 30 kW over a period of 770 ms.
