Description
Description
In this project, the steady airflow over a ventilated air cavity is investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The three-dimensional geometry of this project has been produced with Design modeler software and consists of a cavity placed within a rectangular domain.
The meshing of this project has been done with ANSYS Meshing software, and the total number of elements is 803616.
Ventilated Cavity Methodology
In this project, steady airflow over a ventilated air cavity is investigated by ANSYS Fluent software. The simulated cavity has a hole extending in the flow direction all over the cavity length, making the simulation more challenging.
Fluid flow over objects is important since the results are useful in several branches of fluid mechanics, such as aerodynamics. A built-in hole in the cavity geometry enables flow penetration inside the cavity.
It reduces the pressure drop upstream and downstream of the cavity, which decreases the drag force exerted on the cavity by the airflow.
Airflow velocity at the inlet boundary condition is equal to 1.7 m/s. Due to high flow velocity, the K-epsilon turbulence model is chosen for solving fluid flow domain equations.
Ventilated Cavity Conclusion
At the end of the solution process, two-dimensional contours related to pressure, velocity, and streamlines are obtained. As can be seen, the maximum velocity captured in the domain is equal to 2.32 m/s which occurs on the leading edge of the cavity.
Also, using the data extracted from the Fluent, the air mass flow rate at the outlet is equal to 6.747232 kg/s. The drag force for the cube is equal to 0.0001168629 N.

Kellen Boyer –
I’m impressed with the level of detail in the Ventilated Cavity CFD Simulation project. The K-epsilon turbulence model seems particularly well-suited for the high-velocity conditions described. Is this turbulence model generally the best choice for these types of aerodynamic simulations in practice settings?
MR CFD Support –
We appreciate your compliments on our Ventilated Cavity CFD Simulation training. Indeed, the K-epsilon turbulence model is widely used for high-velocity and fully turbulent flow conditions thanks to its accuracy and reliability in predicting the average flow field characteristics. However, for simulations where accurate wall-bounded flows or areas close to the wall are of interest, or for flows with significant curvature, rotation, or where adverse pressure gradients are present, more advanced turbulence models, like the SST k-omega or LES models, might be required. It is always advisable to consider the specifics of each case when choosing the most suitable turbulence model.

Sammy Gusikowski –
This training helped me understand the complexities of ventilated air cavity flows, and I’m quite impressed with the depth of the simulation. Could you provide insights on how the pressure drop is quantitatively influenced by the ventilated cavity compared to a non-ventilated setup?
MR CFD Support –
The presence of the ventilated cavity allows the high-velocity airflow to penetrate, which alleviates the buildup of high pressure on the front face of the cavity and decreases the suction peak behind it. This typically results in a lower pressure drop across the cavity when compared to a non-ventilated setup. The actual numerical value for the pressure drop can vary based on specific geometry and flow conditions, and ANSYS Fluent allows for precise quantification of this parameter during CFD analysis.
