Acoustic CFD Training Package by ANSYS Fluent Simulation
Acoustic CFD Training Package by ANSYS Fluent
Environmental noise (acoustic) can have significantly adverse effects on our everyday lives, including interference with communication, sleep disturbance, learning acquisition, annoyance responses, performance effects as well as our health through cardiovascular and psycho-physiological effects. Product designers and engineers at the world’s most innovative and successful companies have recognized this fact, and incorporate effective noise mitigation elements into their product design process.
This CFD training Package contains 3 different projects of:
1. Plate Silencer (muffler) and Sound Absorption CFD Simulation:
The present problem simulates the sound pressure waves absorbed by a plate silencer using ANSYS Fluent software. To simulate and analyze sound or acoustic waves, we apply acoustic model in the ANSYS Fluent software.
2. Acoustic CFD Simulation in a Turbojet (Intake Fan):
The present problem simulates the air flow inside a turbojet and examines the acoustic wave and the sound produced inside this turbojet. The model includes a turbojet that has a fan at its inlet. This fan is rotating at 2000 rpm and around the X-axis in the current model. Therefore, we define an area of airflow around the fan, which is using Frame Motion. This turbojet is moving in the air with a Mach number of 0.5, which indicates that the flow can be considered compressible; Because the value of Mach number is more than 0.3.
3. Sound Generation on Airfoil CFD Simulation:
The present problem simulates sound pressure waves around an airfoil using ANSYS Fluent software.
Both Broadband Noise Sources and Ffowcs-Williams & Hawkings methods are applied for the CFD simulations.
There are a Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
