Moving Mesh ANSYS Fluent CFD Simulation Training Package for ADVANCED Users
This training package includes 10 practical Moving Mesh exercises using ANSYS Fluent software. MR CFD suggests this package for ADVANCED users familiar with elementary Moving Mesh theories and simulation and wants to become professionals.
Paper Validation
Project number 1 simulates the airflow passing over an H-type Darrieus wind turbine. The simulation is based on a reference paper, “Wind tunnel and numerical study of a small vertical axis wind turbine.” Its results are compared and validated with the results in the article. In this project, the airflow enters the computational domain with a velocity of 5.07m/s, and the RNG k-epsilon model is exploited to solve the turbulent flow equations, as the paper stated.
Project number 2: Using a spherical turbine based on a lift-based in-pipe, this paper “Numerical analysis of lift-based in-pipe turbine for predicting hydropower harnessing potential in selected water distribution networks for waterlines optimization” model simulates the possibility of operating a power plant inside a pipe. Turbine hydrofoil profiles are manufactured using NACA airfoils. In this project, we intend to simulate the water turbine inside the pipe using the mesh motion method and compare the results with the results in the article. The mass flow is equal to 111 m^3/s, and the rotational speed is 153,626 rpm.
Wind Turbine
Vertical axis wind turbines were the first means of obtaining wind energy. In project number 3, We are simulating a vertical axis wind turbine (Helical Blade) with dimensions of 10 x 20 cm with an average diameter of 7 cm in the present. 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.
Archimedes Screw Generator
Archimedes Screw Generator, also known as Archimedes Screw Turbine (AST), or screw turbine, is a hydraulic machine that uses the principle of the Archimedean screw to convert the potential energy of flow on an upstream level into kinetic energy. In project number 4, an Archimedes Screw Turbine consisting of 3 blades is simulated in two models. The first model is an unsteady Frame Motion, and the second one is an unsteady Mesh Motion.
Mixing Tank
In project number 5, Side Entry Mixing Tank, which has been done by the CFD numerical simulation method, a mixing tank has been simulated. The mixing process is essential in many industries; for example, in the oil and gas industry, water deposition causes much damage to storage tanks, which causes corrosion, leakage, and perforation of the source. This simulation is performed with the Mesh Motion method at different rotational speeds of 400 and 900 and 1400 rpm.
Aircraft
Propulsion is a device used to convert mechanical force into thrust in aircraft and ships. The movement of air or water provides the necessary thrust. A propeller consists of two or more twisted blades. When the propeller rotates around its axis, the lift produced by these blades moves the air horizontally. In project number 6, the thrust and lift forces analysis behind the propeller on the fuselage is examined.
Airplane washing is done several times during the year. Airplane windows are also sensitive parts that can be easily scratched, and it is best to cover these parts before starting the washing process. Project number 7 was performed to simulate aircraft washing. The computational domain of a cube with dimensions of 46 x 8.5 x 17, in which a separate part is provided to move the sub-domain of the aircraft using the sliding mesh model. Water enters the computational domain through holes in the bottom of the slope at a speed of 15 meters per second and air in the opposite direction of the plane at a speed of 2 meters per second from the opposite side to model more realistic conditions.
Pelton Wheel
The water wheel is an example of Pelton turbines. Most water wheels are mounted vertically on a horizontal axis and mounted horizontally on a vertical shaft. In project number 8, the rotational speed of the Pelton turbine is 60 rpm. The two-phase model also uses the VOF model. Water velocity is considered to be 3 to 5 m/s depending on the average river velocity. And accordingly, the rotational speed of the turbine should be calculated with no drag or bump in the flow.
Acoustic
Acoustics is a science that deals with the study of mechanical waves in gases, liquids, and solids, including vibration, sound, ultrasound, and infrasound. In project number 9, noise generation due to a ceiling fan in a room is investigated. The problem is simulated in two ways; at first, the Integral Method by Ffowcs Williams and Hawkings is used in which the fan is rotating by the Mesh Motion method at 240 rpm. In this case, the noise generation due to the collision between wind and the fan is examined using Method Based on the Wave Equation.
Sloshing
Project number 10 investigates the rotation of a cube containing water. The interaction of water and air inside the cube is modeled using the Volume of Fluid (VOF) multiphase approach. This project investigates the simplified sloshing effect in fluid containers where a situation similar to the one studied here can occur due to the acceleration of the carrier vehicle. A User Defined Function (UDF) defines the variable angular velocity of the cube’s rotation.
You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
