Abstract
A small turbine, working with air and water to generate electricity, was designed and its performance was reported in this paper. The rotor diameter is 150mm. The numerical calculations of the power coefficient, torque, and tip speed ratio of turbine were carried out for a wide range of inlet velocities. The flow passing through the turbine was investigated with commercial CFD code ANSYS CFX 18
Highlights
The number of hydrokinetic devices for the utilization of wind and water current energy has been increasing over the recent years
A clear example for that is the turbine of the company “Seaformatics“, which is adapted to work both in air and water
This study shows the aerodynamic design of a horizontal-axis wind turbine blade operating with air and with water using CFD modeling with ANSYS CFX
Summary
The number of hydrokinetic devices for the utilization of wind and water current energy has been increasing over the recent years. The elements of such devices can be manufactured relatively if using the 3D printing technology. A clear example for that is the turbine of the company “Seaformatics“, which is adapted to work both in air and water. It should be kept in mind, that when we speak about renewable energy sources, serious attention should be paid on the production technology. Hydrokinetic turbines can be combined with solar panels, fuel cells and other well-known in the practice equipment for the utilization of the energy from renewable sources
