✦ Synopsis
The computational method is presented for the 3-dimensional nonstationary temperature fields in the UNK SC dipole during its cooldown from 290 to 4.5 K. The method uses 1-dimensional equations for gas and a 2-dimensional heat conductivity equation for the dipole cross-section. The latter equation takes into account the interplay between the elements along the longitudinal axis. The temperature distributions were used in determining the thermomechanical stresses in the helium cryostat pipes. The computational results are compared with the experimental data.
