Renewable Energy – ANSYS Fluent Training Package, 10 Practical Exercises for ADVANCED Users

This training package, including 10 different practical exercises for ADVANCED users, insets Computational Fluid Dynamics (CFD) methods and materials for designing, simulating, and dissecting applied and Renewable Energy Engineering CFD projects, with practical experiments using ANSYS Fluent software.

In the INTERMEDIATE package, we investigate the WIND energy. So, in the ADVANCED package, we are going to study the WATER and SOLAR energies.

Water Energy (Renewable Energy)

Water Turbine

AST

In project number 1, an Archimedes Screw Turbine consisting of 3 blades is simulated in two models. The first model is unsteady Frame Motion (MRF), and the second one is an unsteady Mesh Motion. Considering the conception of both methods, the turbine in the frame-motion method is in a stationary state, and the fluid around it is rotating, while in the Mesh Motion method, the rotating zone that contains the Screw Turbine rotates independently.

Pelton Wheel

A PELTON Wheel is simulated in practical exercise number 2. The water wheel is an example of Pelton turbines. Most water wheels are mounted vertically on a horizontal axis, and can also be mounted horizontally on a vertical shaft.

HAWT

Study number 3 investigates the water flow on the Horizontal axis WATER turbine (HAWT) blades so that the purpose of the problem is to investigate the distribution of velocity and pressure on the wall of the blade. There are two areas around the blades, including a cylindrical area just around the blades and a large area around the cylinder. The flow of water in the large outer space behaves like a normal flow, while in the cylindrical region around the blades, the rotational flow is caused by the rotational motion of the blades.

VAWT

Problem number 4 simulates the water flow around a Vertical axis WATER turbine submerged in water using the DYNAMIC MESH method. The water turbine is from the category of vertical axis turbines and is of the Darrieus type; So that the axis of the turbine is perpendicular to the direction of water flow.

Study number 5 investigates the water flow around a vertical water turbine considering unsteady CFD simulation and FLUID SOLID INTERACTION (Fluid Structure Interaction). In the present case, it is assumed that the turbine blades are affected by the flow of the passing fluid; that is, the fluid flowing through the turbine blades impedes forces on the turbine body and these forces cause deformation or resizing of the body of these blades. Therefore, the present problem consists of two fluid and solid solutions at the same time and hence, the FSI method and the coupling between the fluid flow and the Transient Structural are used.

Solar Energy (Renewable Energy)

Solar Still & Desalination

Study number 6 investigates the performance of a 2-D solar-still thermal desalination unit. The present model consists of a small chamber with a sloping glass surface at the top. The solar heat passes through the glass to the surface of the water in the enclosure and causes surface evaporation (applying a UDF for surface evaporation). Study number 7 investigates the performance of a 3-D solar-still thermal desalination unit. The resulting vapor impact the cold glass surface and undergo a distillation process. Pure water from hot vapor distillation moves down the slope of the glass plate and discharges as pure water.

In project number 8, the surface evaporation process in a 2D solar desalination system is simulated and analyzed. In this process the surface of the fluid water will receive the warmth of solar rays, then based on the principles of surface evaporation, the water molecules on the surface of the water will start to evaporate. Finally, when the gauge pressure and temperature of water vapor reach 3000 Pa and 343.15 K respectively, it will leave the desalination system through the defined pressure outlet. Study number 9 investigates the performance of a STEP solar desalination unit. The present model consists of a small chamber with a sloping glass surface on both sides and steps within it, where saline water flows on the surface of these steps. Solar radiation heat transfer passes through the glass to the surface of the water in the enclosure to evaporate the water surface on the step walls.

Solar Collector

Finally, problem number 10 simulates heat transfer within a PCM solar collector. The current model consists of a U-shaped tube that carries water flow. Around this U-shaped tube, a cylindrical space is used, composed of phase change material (PCM).
