Comprehension of CFD Simulation of Mountain External Airflow Considering Heat Transfer
Project Description
This study analyses airflow and heat transmission across a mountain terrain, crucial for understanding air passageways for aeroplanes. The simulation is conducted using ANSYS Fluent.
Model Design
Designed in ANSYS Design Modeller, the computational domain consists of three distinct pressure outlets, the mountain, and an airflow intake. The geometry is covered by an unstructured mesh of 1,250,044 parts.
Methodology
Air enters the domain at a speed of 8 m/s and a temperature of 297.5 K. To take heat transfer into account, the Energy model is activated. The k-epsilon Standard model is used to examine the turbulent flow dynamics since it is expected that flow separation and vortex creation will occur.
Conclusion
Using 16-time steps and a step size of 7 seconds, the simulation is transitory. Results show contours of pressure, velocity, temperature, streamlines, and velocity vectors, so illuminating the flow behaviour around the mountain.
