Mountain External Airflow CFD Simulation Considering Heat Transfer, ANSYS Fluent Tutorial
The study of natural phenomena has always been of interest to researchers. This project aims to study the airflow and its heat transfer on the surface of the mountain it encounters in the passage, which is also effective in determining the air passage for the aircraft.
The geometry of this model is designed in the ANSYS design modeler and is meshed in ANSYS meshing. The computational domain consists of an airflow inlet, the mountain itself and 3 different pressure outlets (including top and side walls), and the main outlet.
The mesh type used for this geometry is unstructured, and the element number is 1250044.
In this project, the air enters the computational domain with a velocity and temperature of 8 m/s and 297.5 K, respectively. The Energy model is activated.
Due to the nature of the external flow type and considering the airflow velocity, which has consequences such as flow separation and vortexes behind the mountain, the K-epsilon Standard model, has been used to analyze the turbulent flow.
The present simulation and its results are Transient. 16-time steps with a step size of 7 seconds are exploited for this simulation. Then, contours of pressure, velocity, temperature, streamlines, and velocity vectors are presented.
