Container Effect on Truck Aerodynamic CFD Simulation
description
Aerodynamics is a part of mechanics that is very important in car design. This is even more important when designing a truck; Because these cars have more weight, the air resistance in their movement should be reduced as much as possible to have better forward movement. Drag force means air resistance to forward motion and is one of the most important forces to be considered.
The aerodynamic CFD simulation of the truck and the drag force calculation helps us have a good prediction of different forces, especially the drag force around the truck. This directly impacts the truck’s fuel consumption and is essential from an energy and environmental perspective.
This project aims to investigate and analyze the drag force on the truck and compare it in two cases with and without a container by ANSYS Fluent software.
First, the truck’s geometry is designed in Solidworks software and Design Modeler software. The geometry is prepared to create meshing and name selection; then, it is implemented in ANSYS Meshing software. Also, the mesh type is polyhedral, and 663,127 and 1,095,371 elements are produced for ‘truck‘ and ‘truck and container,’ respectively.

Container Effect on Truck Aerodynamic CFD Simulation Methodology
The flow simulation and investigation have been done by comparing the two truck modes with and without containers. We chose the k-w SST turbulence model with standard wall function to obtain better results in our simulation. The pressure and momentum coupling method is SIMPLE.
The solver used is pressure-based.
conclusion
Descriptions of geometry, meshing, boundary conditions, fluid properties, Y-plus (Y+) criterion, and results are in order. In both modes, speed, pressure, and drag force will be examined, and we will introduce the best possible mode for drag reduction.
The results show that the drag force is less in the absence of the container than in the presence of it. This means that it is better to move the truck without the container. Of course, if the problem is done locally in the two parts of the back of the truck and the back of the container, the presence of the container will delay the separation of flow in the back of the truck.
On the other hand, the delay in separation causes the flow from the end of the container to cause less drag due to the smaller angle than the edge of the roof of the new truck. The images related to the flow lines in the back of the truck and behind the container show that the intensity of the vortices is effective from the angle of the top edge of the truck in the back of the truck in empty truck condition. This result can also be seen in the pressure coefficient diagram for comparing the two.

Caitlyn –
Hi. At the beginning of the tutorial, it was shown that the transient solver is selected, but at the run calculation tab, it was shown that a steady solver type is selected. Would you please explain that?
melika maysoori –
Hi, Caitlyn. Thank you very much for your attention. This is explained in the tutorial video because this product was originally supposed to be simulated in transient. This product is going to be modified and updated. However, you can do the simulation in transient. In the general section, select the transient mode instead of the steady mode, and then set the time step in the run calculation section. Let us know if you need more information. 😉

I didn’t understand how to convert 3D elements into polyhedral elements. Where is the convert tab?
melika maysoori –
Do not worry. I’m gonna explain u. :). To convert the entire domain of your mesh, use the Mesh / Polyhedra / Convert Domain menu. ( In fluent software). But note that conversion of a mesh to polyhedra only applies to 3D meshes that contain tetrahedral and/or wedge/prism cells. Hexahedral cells remain unchanged during conversion.

Miss Ramona Price III –
I found the section mentioning Y-plus (Y+) criterion intriguing. Could you give a bit more details on how the Y-plus values were ensured to be within an acceptable range to provide accurate results for the boundary layer?
MR CFD Support –
In this simulation, achieving a suitable Y-plus value was critical for accurately capturing the boundary layer characteristics, which directly influence the aerodynamic forces. As is standard for CFD simulations, the mesh was refined near the truck’s surface to reduce the Y-plus value and ensure that it falls within the appropriate range for the chosen turbulence model. In this case, the k-w SST turbulence model typically requires a Y-plus value close to 1 to accurately resolve the boundary layer without the need for wall functions.
