Fluid flow in narrow gap between two cylinders induced by pressure gradient
 Bartková, Tamara ; Štefan, David (oponent) ; Štigler, Jaroslav (vedoucí práce)
This thesis is focused on the description of fluid flow through an annulus pipe. The flow is examined for various conditions, leading to laminar as well as the turbulent regime. This paper contains research part which depicts known relations describing this particular flow type and means for measuring velocity profiles. The following part contains an overview of creating computational model, flow simulations with specific conditions and their evaluation. Results from the simulations are used in the description of turbulent flow characteristics. These characteristics are then used in the ensuing part, which aims to obtain relation defining time centred mean velocity profile for turbulent flow through annulus.
