Abstract: | A nonstationary method allowing simultaneous determination of the thermal conductivity and diffusivity of metals using an electronic heater is described.Notation qe
heat flux density
- t
temperature
- x
distance to thermocouple
-
heating time
- t0
temperature at time zero
-
thermal conductivity of material examined
-
a
thermal diffusivity of material
- c
coefficient describing the energy losses
- X1, x2, x3
distance to first, second, and third thermocouples, respectively
- 1, 2, 3
times during which specimen is heated to temperature t at points X1, x2, X3, respectively |
