Analysis of fluid flow and heat transfer in district heating pipelines using the finite element method
(2002) Heat Transfer VII, 2002 4. p.13-22- Abstract
- The finite element method is applied to solve coupled steady-state fluid flow and heat transfer problems in insulated pipes of district heating networks. The main advantage of the finite element method involved here is the standard discretization and solution technique for both coupling of temperature-dependent physical properties in the thermo-hydraulic flow and for description of the multilayered structure of insulation, which may also be situated in the environment, such as soil or air. In order to describe the above problem in a standard manner, the complex thermo-hydraulic macroelement has been proposed. This element presents a combination of a standard hydraulic pipe element and one-dimensional thermal elements of the ANSYS code. The... (More)
