||Application of the finite element method for modelling of districtheating network

||This paper presents simultaneous modelling of the fluid flow and heat transfer in a district heatingnetwork. The finite element method is applied here. A major advantage of the finite element methodis the efficiency of verified numerical procedures and standardized information describing the fluid,which may be transferred and communicated with other computer aided design or monitoringsystems.The thermal-hydraulic pipe element of the ANSYS code is modified for these purposes bymodelling the real structure of the pipeline, the heat conductivity and convection. The finite elementmodel is compared to the traditional H.Cross method. A fragment of the district heating system ofthe city Vilnius, Lithuania is used as an illustrative example.
