Aerodynamic & Aerospace ANSYS Fluent Training Package, 10 Practical Exercises for INTERMEDIATE Users
Aerodynamic & Aerospace ANSYS Fluent CFD Simulation Training Package for INTERMEDIATE Users
This training package includes 10 practical aerodynamic and aerospace engineering exercises, using ANSYS Fluent software. MR CFD suggests this package for all aerodynamic and aerospace engineers who will learn CFD simulation in this field at the INTERMEDIATE level.
In practical exercise number 1, a wind tunnel and a specific body that is placed inside it, are modeled considering compressible flow. The effect of drag force on this body is investigated. The energy model and standard k-epsilon model with the use of standard wall functions are activated. Project number 5 is going to study a Supersonic Compressible Flow adjacent to an F-35 plane. The geometry is a 20-meter F-35 plane inside a 150-meter wind tunnel. The air is considered a compressible ideal gas, and the Mach number of 2.0 was achieved at the maximum speed of 544 m/s. Problem number 7 simulates the compressible airflow around the aircraft wing with a flap and slat. In this project, a 3D airplane wing is designed; In such a way, a Flap is on the trailing edge, and a Slat is on the leading edge of the wing.
In study number 8, the effect of different altitudes of a high-speed drone has been studied. The fluid is air, and we considered it as a compressible ideal gas. The maximum speed of the drone is 30 m/s, and the investigated altitudes are 20m and 2000m as low and high altitudes, respectively.
Acoustic in Aerodynamic
Problem number 2 simulates sound pressure waves around an airfoil. This project examines the sound waves generated around the body of an airfoil. In this project, an acoustic model in Fluent software has been used to simulate and analyze sound or acoustic waves. The Broadband Noise Sources model has also been used to define the type of acoustic model of the present work. Problem number 6 simulates sound pressure waves around an AUDI car with and without a spoiler. Aeroacoustics is a branch of acoustic science that investigates the production of Noise. In general, Noise can be generated by the movement of turbulent fluid or from collisions of aerodynamic forces with surfaces.
Moving Mesh (Mesh Motion) & Dynamic Mesh
In project number 3, rotation of helicopter wings are simulated in transient time formulation and the results including net upward force, wing tip speed and Tip Speed Ratio (TSR) are investigated. In order to generate upward movement in aerodynamic applications, movement of a certain amount of air in the downward direction is needed, which in return generates upward motion. For helicopters, this movement of air is done using a propeller which consists of 2 or more wing-shaped geometries, rotating around a center. In practical exercise number 4, a golf ball movement with an aerodynamic point of view has been studied applying Dynamic Mesh, the force which is applied to the ball is equal to 200 N. The golf ball displacement due to the impact, has been studied in terms of time.
In project number 9, the analysis of thrust and lift forces behind the propeller on the fuselage is examined. Aircraft and propeller modeling is performed in two zones rotational and stationary. The rotating computational domain must rotate around the impeller axis to model the impeller rotational motion using the Mesh Motion method.
Pressure-Based & Density-Based Solvers
Finally, In practical exercise number 10, the aerodynamic coefficients of a Formula One (F1) car by two different solvers of pressure based and density-based, has been studied, at a speed of 108 meters per second at a lateral angle of zero degrees (actually a straight path). This velocity at the ground level is equivalent to Mach number approximately 0.32. We know this area from Mach number is the transition zone from incompressible to compressible flow, so on this geometry, the drag coefficient is investigated using two pressure-based and density-based solvers is discussed.
