Estimation of power performances and flow characteristics for a Savonius rotor by vortex particle method

This study investigates the implementation of the vortex particle method (VPM) with the goal of efficiently and accurately estimating the power performances and flow characteristics for a Savonius rotor. The accuracy and efficiency of simulation methods are critical for the reliable design of Savonius rotors. Among various approaches, VPM is...

Recent advances in understanding the flow over bluff bodies with different geometries at moderate Reynolds numbers

The application of unsteady incompressible flow phenomenon over the bluff bodies has received the attention of many researchers due to the rich and complex physics underpinning these flows, and thus requiring special attention in their modelling and numerical simulations. The wake that forms at the leeside of the bluff body is of particular...

Mound Breakwaters under Wave Attack

Research on rubble mound breakwaters when confronted with waves. The rapport covers the flow characteristics and mound stability under regular waves and under oblique wave attack. The authors find a formula for rough, permeable slopes, flow characteristics under the action of a regular wave train by a function of the type. Furthermore they...

Measurements in a 2-D wake and in a 2-D wake merging into boundary layer: Data report

Extensive measurements of mean and fluctuating quantities in a 2-D wake shed from a flat plate and in the flow field of a 2-D wake merging into a boundary layer are described. The 'results are given in tabular and graphical form.

Characteristics of Subcritical Flow in a Meandering Channel

The flow in a meandering channel is complicated by its curvi-linear characteristics. Consequently, spiral motion and superelevation develop, and the velocity and boundary-shear distributions are modified. Through an approximate theoretical solution and experiments in a fixed-bed model of constant radius, central angle, and uniform cross section,...
