The understanding of the performance of a propeller in realistic operative conditions is nowadays a key issue for improving design techniques, guaranteeing safety and continuity of operation at sea, and reducing maintenance costs. In this paper, a summary... see more

This paper proposes a radial-shear mill (RSM) of a new design, which allows by rolling or rolling and pressing operations obtaining high-quality rods and wires. In addition, it proposes the method of computer calculation of the energy-power parameters of ... see more

The aerodynamics of contra-rotating propellers is a complex three-dimensional problem of an unsteady flow, which is often approached by assuming numerous simplifications. Presented computational model combines a 3D panel method with a force-free vortex wa... see more

Experimental data obtained by measuring the tangential component of force affecting radial baffles in a flat-bottomed cylindrical mixing vessel stirred with pitched blade impellers is analysed. The maximum mean tangential force is detected at the vessel b... see more

Experimental data obtained by measuring the tangential component of the force affecting radial baffles in a flat-bottomed cylindrical mixing vessel stirred with a Rushton turbine impeller is analysed. Spectral analysis of the experimental data demonstrate... see more

A low-order panel method is used to predict the performance of ducted propellers. A full wake alignment (FWA) scheme, originally developed to determine the location of the force-free trailing wake of open propellers, is improved and extended to determine ... see more

The availability of non-renewable energy has recently been running low and so impacts electrical energy. Renewable energy is converted from natural sources to kinetic energy. The Double Propeller Water Turbine is a water turbine that is suitable to be app... see more
