Prediction of heat losses from district heating twin pipes
Paper in proceedings, 2008

A method for calculation of long-term heat losses from polyurethane foam insulated twin pipes is presented, accounting for the spatial dependence and time variation of the insulating capacity of the foam. With aid of a coordinate transformation the cross-section of the twin pipe is mapped onto a rectangular geometry, which facilitates the modeling. Preliminary results given by the new model are compared to results given by a previous model.
