Numerical analyses of trash racks characteristics under different exploitation conditions in hydropower plants
Abstract
This paper represents a research about the influence of different operational conditions on trash racks characteristics. The main goal of the research was to find to how the specific parameters of the trash racks (flow velocity, head loss and head loss coefficient) change in the various exploitation situations. The comparison was done by looking at the cases of the normal flow (flow is perpendicular to the trash rack’s frontal area) and inclined flow (flow takes different angles). All of the mentioned cases were analysed by running simulations based on the branch of fluid dynamics called computational fluid dynamics (CFD). In both cases simulations were based on the steady flow, while the normal flow case was analysed with both steady and unsteady flow simulations.
