Dear TRNSYS users,

I would like to model an open concentric tube heat exchanger where the
circulated water is in direct contact with the ground, in other words there
is no outer pipe. What is your opinion on using Type 557d with zero
thickness of the outer pipe to approximate this? Would this be a crude
approximation?

Best regards,
Knut Erik Enerstvedt
