Automotive aerodynamics is the study of the aerodynamics of road vehicles. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case. For some classes of racing vehicles, it may also be important to produce downforce to improve traction and thus cornering abilities.

The first design of the car is on the left collum. The improved and redesigned car is on the Right side collumm.
First Flowsim
First Design (airflow sim)
This simulation shows how much resistance is being put on the car by wind. The less red there is in one area the better. The front of the car had poor airflow as you can see.
Below is the print preview of the Car
Second Flowsim
Gif of Airflow with arrows and colors
The redesigned car was abel to have more effiecent airflow as you can see. The curved shape of the car created less red areas on the front of the car which will allow it to go faster in the end.
Improved Redesign
Below is the print preview of the car

The sheet above is showing the amount of lift on the car based off of the flow sim results.
Excel sheet results from flow sim. This chart is showing the amount of lift.

The sheet above is acheiving the same thing just for the Drag on the car.
Excel sheet result from flow sim (Redesigned car)
The sheet above is doing the same thing but it is for the drag on the car

Post Processing Videos/Images
Above is a preview slice of the print for my car. The car printed overnight and was sucessfully printed. To the left you will see my completed race car.
Race Day #1
My car finished with a time of 1.512 seconds this day. I was racing in the thin tires category and placed second overall for the day.
Above is my work for calculating the maximum velocity
Race Day #2
My car finished day number 2 with a time of 1.541. My car was once again in the podium for thin tires in the MID session for the day.
Above is my work for calculating the maximum velocity
Race Day #3
Above is my work for calculating the maximum velocity
Day 3 was the fastest day for my car finishing with a time of 1.317. My car finished all three days on the podium for thin tires in the MID session.
Average total Velocity
The average feet per second rounded to 53.298.
