Turbomachinery CFD Simulation Package, ANSYS Fluent Training fro ADVANCED Users

This CFD training package is prepared for ADVANCED 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.

Water Turbine

In project number 1, an Archimedes Screw Turbine (AST) 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.

Study number 2 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.

In project number 3, a water wheel as an example of Pelton turbines is simulated. Most water wheels are mounted vertically on a horizontal axis, and can also be mounted horizontally on a vertical shaft. The wheels are perpendicular to certain parts of the turbine due to reduced friction force and increased nozzle thrust.

Study number 4 investigates the water flow around a vertical water turbine considering unsteady CFD simulation. 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.

Compressor

Problem number 5 is going to simulate the airflow inside an axial flow compressor (Rotor Nasa 37). The present model consists of a series of blades for an axial flow compressor connected to the central axis within a cylindrical area. To simplify the simulation model, only one row of rotating blades is drawn on the central rotor of the compressor.

Problem number 6 simulates the air compression inside a Rampressor. The Rampressor is a unique type of ultrasonic compressor rotor that operates at a high-pressure ratio, and engine technology and gas compression are the ramjet ultrasonic shock wave. The operating mechanism of these compressors is such that the gas flow passes through a fixed outer cover and a sloping surface or inner ramp.

Mixer (turbomachinery)

In project number 7, a mixer tank is modeled and the effect of its rotating impeller on the mixing procedure is investigated. The simulation is done using the VOF model for the three phases of air, water, and salt. The k-epsilon model is applied for solving the turbulent flow inside the tank.

Impeller

In project number 8, the airflow passing over an impeller of an electrical motor is investigated. The airflow enters the computational domain with 80m/s, and the impeller rotates with 1000rpm. A Realizable k-epsilon model is exploited to solve turbulent flow equations.

Fan

In project number 9, steady airflow in a 3D geometry of the fan stage is simulated. Fan stage is a common apparatus used for creating steady airflow in industrial applications used in the cooling process of newly painted body parts. The periodic boundary condition is used for simulation of the real fan stage at the lowest computational cost.

Wind Turbine (turbomachinery)

Finally, in problem number 10, we are simulating a small-scale VAWT with helical blades. We are simulating a wind turbine with dimensions of 10 x 20 cm with an average diameter of 7 cm in the present problem. This simulation was performed at wind speeds of 2 m / s and speeds of 60-40-80-100-120 rpm, and torque was reported as output.
