Wind Tunnel Testing | Project Sierra Log#2



The wind tunnel had its first successful test!! On the 21st of January 2023 at 3:17 pm Project Sierra had its first successful test where I tested the aerodynamics of a model of a Lamborghini Aventador and a Bugatti Divo. After the initiation of the project’s construction back on October 6th, 2022 it has been a long wait for the required parts, but it was Worth It!!

In all honesty, the Lamborghini did not test well even though it definitely looked like the better of both models, aerodynamics-wise. Granted there are definitely a lot of modifications needed to make the wind tunnel run to an optimal level. The following are the improvements currently being made:

  1. I’m currently 3D printing a stand to raise the test model to a level, where the test model will be in the middle of the test chamber to receive the most pressurised air

  2. Higher and stronger support for the wind tunnel as the current support nearly collapsed after testing

  3. To find the optimal RPM of the fan (I can adjust it thanks to my booster module)

  4. To reduce the amount of fog emitted by the fog machine to keep the test object actually visible rather than in a puff of smoke

Although the wind tunnel currently has its flaws, I still consider it a victory as the air managed to remain streamlined and I managed to actually keep it airtight!! Moreover, I don't think a lot of 17-year-olds have built wind tunnels with the calculations to recieve optimal data on drag, and airflow around the object. I also added a 3D-printed scissor lift to bring the test platform up to the wind tunnel. I cannot wait to test more models and maybe even test a few that I developed.

Project Sierra is undoubtedly a major milestone for me!!

I made my very own CFD Software!! | Project Zephyr

Project Zephyr is a CFD software I created using Blender's Particle Physics, Collision, Flow Dynamics Software. It uses the method developed by Joseph-Louis Lagrange to test the amount of drag generated by an object. The Files will be made Open-Source and available to the public. I will be making a tutorial on how the Software would work along with what the user can change to test different things. Alright! Time to rant! Project Zephyr is an extension of Project Sierra, as anyone in the car industry would tell you they use CFD Software to first, digitally test their designs before heading to a wind tunnel facility. Hence I decided to do the same. Yesterday I spent a good few hours trying to download a free CFD software called Openfoam which required me to make a virtual machine that ran linux, which was a pain in my ass! as Ubuntu(the software I was using to make the virtual machine) kept telling me that there was an unexpected error. After an Hour I was able to create the linux vi...

Ahhhhh! Korean Ramen, is one of the hottest Asian dishes. It has everything your palette craves, it has fresh herbs to give liveliness, meat for your more naughty desires, caramelised onions for the sweetness, and the classic half-cooked egg for the nirvana-like syrup that is the yolk. I do have a confession though, when I say authentic, I don't mean I made the ramen from scratch, cause that would take too long and I really don't have that much time!! so it's more like I cooked ramen that came in a packet but all the toppings so to speak are made by me at home. Great now let's Start with the recipe on how to make this lovely treat! First, chop up some onions in a ring-like manner and make sure they are no thicker than 0.5 cm (I mean approximately don't actually use a scale to measure) as that way they can actually caramelise properly. Then finely chop some coriander leaves, this is optional I just feel like it gives some extra colour and gives a little b...
