Modelling of accelerated pipe freezing
The use of pipe freezing as an advanced maintenance technique and the potential advantages of freezing non-circular sections were highlighted in an earlier paper. This work reports in detail on the finite element modelling of the freeze in a non-circular section. The formulation and operation of the model is explained and predicted time-to-freeze compared with the results of new experiments.
