【 摘 要 】
References(35)This paper presents a numerical model for an open axial-flow hydro turbine using moving particle simulation (MPS) method and discusses the torque generation via the model. An Archimedes-screw hydro turbine, which is a type of open axial-flow hydro turbine, has advantages such as ease of installation, durability, and debris tolerance. However, it has been difficult to analyze dynamically due to a complicated interaction between the open channel flow and the turbine. This paper conducted fundamental experiments such as water flow of a dam moved a flat plate and confirmed the validity of the model. The model reproduced well the rotational movement of the Archimedes-screw hydro turbine in an open channel when no-load conditions. Calculated result of rotational speed and torque distribution showed that the turbine gained the rotational torque by mainly the conversion of a water pressure on the blades due to the water level differences. At the upstream end of the screw, torque loss occurred through a wide range of flow conditions.
