Project Sierra | Update Log#1



For Those of you who haven't read my previous post, PROJECT SIERRA is a wind tunnel I am developing to test out prototype car designs for my company. You can click the link below to see the blueprint and read about the necessary calculations i took to start the project: https://www.the-weekend-innovator.com/post/the-wind-tunnel-project-project-sierra

As some of the parts for the wind tunnel have recently arrived (The electronics) I decided to test them to see if I could get a streamlined flow of air through the fan.

I soldered the necessary wiring to the DC booster and the fan that way I could regulate the fan speed to get optimal results, and I must say the results were much better than I had expected as since the tunnel was still not ready I had to test the fan in the open which means that turbulent outside air could effect the test.

Nonetheless, the results speak for themselves, I was able to get the streamlined effect but the smoke was unable to move along the car for a long time as I felt outside air was pulling it away from the experiment zone. I tested a model Bugatti Divo and a Lamborghini Aventador to fine-tune the speed of the fan.

The fan for the test and the wind tunnel would be pulling in air and acting like an exhaust rather than pushing air, as air being pulled has a much lesser chance of turning turbulent and would be easier to get that desired streamlined effect. I would also reduce any vibrations inside the wind tunnel. You can see the footage of the test below. Keep in mind that the camphor which I have used for the test would not be used in the final experiment but it works fine for a test like this. The camphor has also been placed a little too close as since the outside is not closed the fan is unable to pull air in a beam-like form rather it is pulling air from all directions making it less efficient for the test.

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: 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 Higher and stronger support for the wind tunnel as the current support nearly collapsed after testing To find the optimal RPM of the fan (I can adjust it thanks to...

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

Image
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...
