Chilled Pipeline and Frost Heaving

Chilled Pipeline and Frost Heaving

Chilled Pipeline and Frost Heaving

(OP)
Has anyone had experience with calculation of frost bulb growth surrounding a buried chilled pipeline? If so, a link or some tips would be greatly appreciated. I have searched long and hard and have not found anything of use, so if anyone here has experience, I would love to discuss the topic. Thanks.

Talk to people in the pipeline industry that work with nat. gas.

The people at Arctic Foundations may be of help.  Their thermosyphon freezes ground, though usually in a vertical application.

Look in Chapter 12 of this publication for equations for heat loss from buried pipes:

A basic Arctic foundation textbook usually includes "freezeback pile" calculations - time to freeze a soil-water slurry in the annular space around a pile placed in permafrost.  This is similar, but in a reverse direction, to your problem.  You can find the process/equations for this in Chapter 4 of:
