Numerical modelling of the fluid flow at the outlet from narrowed space for a better water management

Popis výsledku v původním jazyce

In the water management, events of significant changes of the running fluid flow space occur very frequently. Such change influences significantly the characteristics of the flow field and thus its effects on the environment. These might be effects on adjacent objects in the close proximity such as walls of the designated space, or effects on objects bypassed with the running fluid. Such situation frequently influences the surrounding area. The flow run may affect the terrain of the land or even the ambient climate in some cases. This chapter is dedicated to problems of numerical modelling of Newtonian fluid flows in changing flow space. Showing a particular task, which is solved numerically using CFD codes (Computational Fluid Dynamics) in ANSYS Fluent software, the reader becomes familiar with both, problems of the mathematical specification of fluid movements and principles of the correct choice of the numerical model. To resolve this task, 4 numerical models are selected. Basic turbulent characteristics of the flow filed are monitored. Outputs of individual models are evaluated and compared with each other. Selected results are also verified by experimental measuring.
