Updated April 7, 2024 at 11:02 by Joshua_1102 (adding information)

Greetings, I am Lok Yong Kheng, currently pursuing a bachelor's degree in Mechanical Engineering.

I have encountered a challenge with my Computational Fluid Dynamics (CFD) simulation. I am seeking assistance with the user-defined function (UDF) code for analyzing the acoustic model in a 2D Transient Thermoacoustic Refrigeration Model. Specifically, I am unable to obtain results for Sound Pressure Level and Acoustic Pressure post-simulation. This difficulty arises from the application...

Updated May 3, 2023 at 16:23 by wa$$im

Turbulence is a complex phenomenon that occurs in most engineering applications involving fluid dynamics. It is characterized by the irregular and chaotic motion of fluid particles, which can cause significant fluctuations in velocity and pressure. Until now, there has not been a single and practical turbulence model that can reliably predict all turbulent flows with sufficient accuracy. whereas many turbulence models have been developed from the perspective of finding different compromises between...
