Turbomachinery CFD Simulation Package, ANSYS Fluent Training for INTERMEDIATE Users

This CFD training package is prepared for INTERMEDIATE users of ANSYS Fluent software in the Turbomachinery area including 10 practical exercises. You will learn and obtain comprehensive training on how to simulate projects. The achieved knowledge will enable you to choose the most appropriate modeling approaches and methods for applications and CFD simulations.

Pump

Problem number 1 simulates the pumping of highly viscous fluid (i.e., Glycerin). In this project, the glycerin fluid is sucked inside the computational domain due to the rotation of screws. The twin-screw pump increases the pressure of the Glycerin and pushes it toward the outlet.

In project number 2, a ram pump has been simulated. In this simulation, a mesh motion model with an angular velocity of 1 radian per second has been used, and the input speed has Water is 1m/s, and at the outlet, water is discharged at atmospheric pressure.

Turbine

Problem number 3 simulates the water flow inside a Francis water turbine. A water turbine is a turbomachinery that converts kinetic energy from water flow or potential energy from water height differences into rotational motion. Francis turbines are one of the types of water turbines that have the ability to use both kinetic and potential energy for power generation at the same time due to the location of their blades.

In project number 4, the water flow passing over the Kaplan turbine is investigated. The Kaplan turbine rotates at 3300 rpm and sucks the water in. RNG k-epsilon model is exploited to solve turbulent flow equations.

In project number 5, we are going to study the hydrodynamics of the Small Size Kaplan Turbine. The geometry included a small-size Kaplan turbine with 125 [mm] as a new prototype. Our static domain consists of 8 [m] long rectangles, and our rotary domain is the Kaplan geometry with 16.5 RPM as the angular velocity.

Wind Turbine

HAWT

Project number 6 will study an incompressible isothermal airflow close to a standard horizontal axis wind turbine (HAWT) considering Turbine BASE. The geometry is a wind turbine with a 30-meter base inside a 300-meter wind tunnel. Also, we select the maximum speed of 1 m/s is for the wind and the turbine velocity of 30 RPM.

Problem number 7 simulates a wind farm with a series arrangement. In this project, four wind turbines are designed in a row in a specific computational domain of ​​a large field called a wind farm (turbine farm). A wind turbine is a piece of equipment in the category of turbomachines that uses wind kinetic energy to generate electricity.

VAWT

In project number 8, a 2-D two-blade Savonius wind turbine has been simulated using moving mesh, and then the results were investigated. Air enters the fluid domain from the inlet with 10m/s velocity while the turbine rotates with a constant angular velocity of 10rpm. Our final goal is to illustrate the pressure and velocity distribution and the fluid motion animation behind the turbine.

Problem number 9 compares the airflow passing over two H-type Darrieus wind turbines of plain and serrated airfoils. In this project, the airflow enters the computational domain with a velocity of 7m/s, and we apply the RNG k-epsilon model to solve the turbulent flow equations. Also, it should be noted that the Mesh Motion option was enabled to simulate the rotating motion of turbine blades, and the rotation velocity of the rotating domain was set to 2.8285 rad/s.

Finally, in project number 10, a 3-D two-blade Savonius wind turbine has simulated, and then the results were investigated. Air enters the fluid domain from the inlet with 10m/s velocity while the turbine rotates with a constant angular velocity of 40rpm. Our final goal is to illustrate the pressure and velocity distribution and animate the fluid motion behind the turbine.

You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.[/vc_column_text][/vc_column][/vc_row]
