“…THD is vertical or horizontal pipe manifold of large diameter with low hydraulic resistance. The beginning of the research was covered in papers [1][2][3], where the main properties and advantages, ways of application, simple mathematic model and results of simulation were given [4,5]. It was assumed that there is thermal stratification along the height of THD and hydraulic independence between circuits.…”

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.

“…In principle, the k RNG model can deal with streamline curvature, swirl and rapid strain (see Appendix A) and is reasonably computationally efficient, requiring the solution of only two additional partial differential equations. The k RNG model is validated against experimental data by Yavorovsky et al [24] for a model of THS bearing some similarities with that considered in the present work (see Appendix C). Further details about the turbulence modelling used in this work are provided in Appendix A.…”

Application of thermohydraulic dispatcher (THD) for district heating systems is, to some extent, limited due to insufficient information about its properties and features. At the same time this device has a potential to solve the problem of mutual dependence of heat consumers and to decrease electricity consumption in heat supply systems. This paper deals with experimental research and numerical simulation of THD with the aim of increasing the range of knowledge about its properties. Presented results describe already known properties such as near-to-zero differential pressure at THD and flow rates independence which were checked. Some new properties and peculiarities of THD were obtained during the investigation as well. Among them is differential pressure "variability", hydrodynamic separation under higher velocity, similarity of thermohydraulic processes inside THD under similar velocities in manifolds of THD, absence of thermal stratification in mixing regime, dependence of secondary circuits supply temperature from the height level and secondary circuits return temperature.
