Analysis of the impact of increasing the efficiency of Savonius turbine working in a hybrid system trough the using of building’s elements as curtains

Kasperowicz Ł, Kurz D.

Computer Applications in Electrical Engineering

2012

Vol. 10

218--227

The paper presents Savonius turbine and the results of worldwide research. Statement was made the most optimal geometric parameters and shows how increase a turbine efficiency of energy generation without interfering with the turbine structures, through the use of appropriately selected curtains. Proposed use of building elements to improve the efficiency of the turbine and to create a hybrid system, attaching photovoltaic panels. Calculated energy yield of the entire system and installation diagram is shown in off-grid system.

Unsteady Flow through the Gap of Savonius Turbine Rotor

The paper presents a numerical analysis of unsteady flow through the gap of a Savonius turbine rotor, performed for varying integral turbine operating parameters calculated for the case under study as well as obtained from experiments described in the literature. Changes in the unsteady flow pattern, including the development and interaction of numerous vortex structures in the vicinity of the gap, and their relevance to the varying integral parameters are discussed. We conclude that the structure responsible for the intensity of the flow through the gap is a vortex which forms in the vicinity of the gap at certain phases of rotor revolution, and that a possible way to improve the efficiency of operation of a Savonius turbine is to control the intensity of this vortex by modifying the shape of the blade edges in the vicinity of the gap.

W artykule przedstawiono wyniki analizy funkcjonowania autonomicznej, hybrydowej instalacji słoneczno-wiatrowej, z turbiną o osi pionowej oraz buforem energii, w warunkach klimatu Polski. Do symulacji wykorzystano 10-letnie godzinowe dane meteorologiczne IMGW dla Warszawy. Przeanalizowano wpływ pojemności bufora energii elektrycznej na zyski cieplne produkowane przez instalacje.

This paper introduces a theoretical analysis of the performance of PV/wind/diesel hybrid system with Savonius turbine and energy storage. We show that in the Polish climate conditions such installation could work effectively. The impact of capacity of the battery bank on the extra heat gains has been investigated.
