Yes, originally it was for a transient, semi-infinite solid based on radial coordinates. However, after some reasearch, it seems much too involved a question which I honestly do not have time for. Instead, I used a much simpler model just to get a general idea... and will hopefully be able to...

Forgot to mention... but obviously the above method also assumes steady state, which I think is a decent assumption for the case I am working on.

Thanks CRG. I'll try and find those from at a library on monday. I am pretty new to this industry... and I would like to know if anyone with experience, could give me a rough estimate at how much frozen ground a pipeline like this would cause? Are we talking, 6", a couple feet, a couple of...

I am working on the following problem: I have a buried pipeline at -5C which is causing a layer of soil X meters above it to freeze after a specified time period. The soil is initially at 5C and known is all the thermal data. In order to model this, I decided to consider the soil as a...

I am working on a specific project in which I need to somehow calculate the frost bulb growth surrounding a buried pipeline. The pipeline is around -4C (Joule Thompson effect) while the surrounding soild is around 5C. The pipe is NPS 8 and uninsulated. The question is, can anyone offer any...

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...
