  2. 1. Hydraulic Efficiency in Pond Design

    Author : Jesper Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance; environmental science; efficiency; numerical modeling; design; hydraulics; pond; wetland; tracer study; preference;

    Abstract : Today there is a growing interest in constructed ponds to treat agricultural runoff, sewage water and stormwater. But ponds not only remove nitrogen, phosphorus and pollutants such as heavy metals; they can also have ecological, social and esthetic values. READ MORE

    Abstract : Irrigation decentralization has been launched worldwide with high expectations of improved governance, efficiency, and productivity through  democratic processes. However, there is widespread recognition that decentralization is, in reality, unlikely to bring about these positive outcomes. READ MORE

  6. 4. Numerical and experimental study of performance of a hydraulic motor

    Author : Leon Dahlén; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic fluid; hydrostatic transmission; hydraulic motor; Engineering mechanics; Teknisk mekanik; Maskinelement;

    Abstract : The aim of this study was to develop an understanding of the fluid properties that influence the efficiency of hydraulic systems in a steady-state, especially components in hydrostatic transmission systems under different running conditions. The aim has also been to investigate and model the sources of losses in hydraulic machines, in order to estimate the losses, taking fluid properties into account. READ MORE
