Wind Turbine |
|
Renewable energy has attracted
significant interest as a next generation energy source.
Wind power is a major opportunity. CFD simulation
can be used to determine the pressure acting on the
turbine blades and structure, calculate torque, and
predict the aerodynamic forces on the environment around
the wind turbine. The image shows isosurfaces of
vorticity created by the wind turbine. |

| Axial Fan |
| Fluid flow analysis of an axial fan is difficult because the blade
shape significantly affects performance. Accurate geometry representation and grid generation is critical. Starting from CAD data, SC/Tetra's automatic mesh
generator can create the computational mesh in a matter of hours. In contrast, most conventional CFD software will require weeks to create the mesh. SC/Tetra
simulates rotating blades using the rotating boundary (ALE) function. In addition, SC/Tetra perform a preliminary steady state analysis using only blade rotating
forces. |
 |
| Sirocco Fan |
| SC/Tetra greatly reduces working hours for simulating a sirocco fan, as
well as a propeller fan. A transient analysis using the ALE function (Arbitrary Lagrangian Eulerian for moving and/or rotating boundaries) can be used to provide more accurate
details over and above a cursory steady state analysis. |
 |
| Blower |
| A blower moves the working fluid with rotating blades similar to other fans. SC/Tetra
can model both gases and liquids. |
 |
| Turbofan (Turbine) |
| The shape and the number of blades greatly affect the performance of a turbofan.
SC/Tetra can be used to evaluate several different cases in a short time because it is possible to build a model by changing only the rotating parts and its area. |
 |
| Vortex Blower |
| The internal flow of a vortex blower, which can rotate in either direction, contains a
highly complex flow that can only be effectly visualized using CFD. CFD is useful for making this complicated flow visible and enabling the user to understand basic flow
structure and physics. |
 |
| Mixed Flow Pump |
| For pumps as well as many fans, blade and housing shape greatly
affects performance. SC/Tetra can model either gases or liquids as the working fluid. |
 |
| Multi-Stage Pump |
The computation of the fluid flow through fans and turbines tends to take a long
time because of the transient phenomenon that occurs between the rotating and stationary components. However, SC/Tetra possesses convenient functions design to
facilitate these analyses. These include the axial symmetric condition, periodic boundary conditions, and treating the rotating force as a rotating object instead of
simulating the actual rotation. These functions can greatly reduce the calculation time while still accurately simulating the physics.
