  • Three dimensional flow at the junction between a

    A visualization of the flow on the suction side and end-wall of a passage between two neighboring turbine blades is compared with mass (heat) transfer measurements on the same surfaces. Besides the horseshoe and passage vortices, there are several smaller vortices formed near the junction of blade and end-wall whose origins are discussed.

  • Three-dimensional boundary layer in a turbine blade ...

    The boundary layer on the end wall of a turbine blade cascade is subject to cross-stream pressure gradients in the blade passage, which generate a cross-stream velocity component to make it three dimensional. This distorts the turbulence relative to a two-dimensional boundary layer and impacts the end wall heat transfer.

  • Numerical and experimental studies of three

    The numerical simulations of hydraulic turbine runners such as Francis and Kaplan runners have widely been carried out by using three-dimensional Euler code with the pseudo-compressibility. However, there are rare cases that include the verifications of the simulation accuracy based on the experimental data.

  • Development of microturbocharger and

    A microscale gas turbine is under development at Tohoku University in Japan. Current objective of the project is to reveal the performance of the gas turbine at microscale with optimum aerodynamic shape. Therefore the engine to be tested will be fabricated by machining using a micro-5-axis end mill to realize three-dimensional modeling.

  • Behavior of three-dimensional boundary layers in a

    A detailed experimental investigation was carried out to examine the three-dimensional boundary layer characteristics in a radial inflow turbine scroll. Some basic flow phenomena and growth of secondary flow were also investigated. In the inlet region of the scroll, the incoming boundary layer begins to have a skewed nature, namely the radially ...
