Turbomachinery CFD Training Package, Beginner Users

Turbomachinery CFD Simulation Package, ANSYS Fluent Training for BEGINNER Users

Today, the use of CFD methods in the design and analysis of Turbomachinery has become very important. The application of CFD in the simulation of turbomachines includes the following:

• Performance Predictions
• Internal flow visualization
• Investigation of existing design
• Qualitative and quantitative validation of performance using simulations.
• Optimization

This CFD training package is prepared for BEGINNER 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 with ANSYS Fluent software. The achieved knowledge will enable you to choose the most appropriate modeling approaches and methods for applications and CFD simulations.

We start the training package with 3 practical exercises about different Horizontal Axis Wind Turbines (HAWT).

Study number 1 deals with the airflow on the HAWT blades so the purpose of the problem is to study the distribution of velocity and pressure on the surface of the blades and on their body. There are three areas around the blades for airflow. There is an area around the blades, an area in the front of the blades, and an area behind the blades. Project number 5 is going to simulate an airflow field adjacent to the Liam F1 wind turbine. The geometry included a rotary zone for the turbine walls and a stationary zone for the rest of the domain. The inlet is considered 3 m/s and the turbine zone is rotating with 300 RPM. Practical exercise number 10 is going to simulate an airflow field close to a standard horizontal axis wind turbine. The geometry included a rotary zone for the turbine walls and a stationary zone for the rest of the domain. The inlet is considered to wind with 1 m/s, and the turbine zone is rotating at 16 RPM.

Then, we continue the training package with 3 practical exercises about different Vertical Axis Wind Turbines (VAWT).

In practical exercise, number 3, steady airflow in the presence of an H-type wind turbine (VAWT) is investigated. Nowadays, turbines are a reliable, clean energy source, which generates electricity using the induced rotation by wind flow. However, turbine wind farms face challenging issues such as low efficiency at lower diameters for horizontal axis wind turbines (HAWT), disruption of the natural view of valleys, and low wind conditions. Project number 7 is going to simulate an airflow field close to a Darrieus (vertical axis wind turbine). The geometry included a rotary zone for the turbine walls and a stationary zone for the rest of the domain. The inlet is considered to wind with 1 m/s, and the turbine zone is rotating with 120 RPM. Practical exercise number 8 is going to simulate an airflow field close to a vertical axis Helical wind turbine. The geometry included a rotary zone for the turbine walls and a stationary zone for the rest of the domain. The inlet is considered to wind with 1 m/s, and the turbine zone is rotating at 120 RPM.

Finally, we investigate different Turbomachinery devices in 4 practical exercises.

In project number 2, steady airflow is investigated between two 3-bladed series fans which are rotating at an angular velocity of 300 rpm. The rotation of fans generates air suction at the inlet boundary with a flow rate equal to 2.95755 m3/s. The velocity of air reaches values up to 25 m/s on the domain centerline however maximum air velocity in the domain is equal to 47.05 m/s which is captured downstream of the first fan. Problem number 4 simulates a centrifugal blower. The blower is a particular device for blowing high-pressure air, which generally has applications such as dust cleaning and …. For example, a blower is used to clean computer parts and equipment. Practical exercise number 6 simulates a centrifugal compressor with a diffuser. One of the most widely used compressors in the industry is the centrifugal-type compressor. This compressor uses positive pressure while using centrifugal force to compress the gas. Project number 9 simulates the airflow inside a 4-row multistage compressor. The compressor designed in this simulation is of axial type and consists of four rows, including two rows of stator and two rows of the rotor. In general, axial flow compressors are compressors whose airflow is parallel to the axis of rotation. Practical exercise number 10 is going to simulate an airflow field close to a standard horizontal axis wind turbine. The geometry included a rotary zone for the turbine walls and a stationary zone for the rest of the domain. The inlet is considered to wind with 1 m/s, and the turbine zone is rotating at 16 RPM.
