Experimental Research of Thermo-Hydraulic Separators and Dispatchers in Heat Supply Systems

Abstract:

This article is concerned with the research of thermos-hydraulic separators and dispatchers (THD) in heat supply systems and focuses on the experimental part of the research. Тhe experiments allowed to develop the ANSYS Fluent model in terms of accuracy and veracity. The developed model allows to predict operation of THD in different regimes. The results may be used for designing the systems with THD. Such systems may be low temperature district heating systems, where THD allow to hydraulically separate the circuits from each other.
