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 virtual machine and even download OpenFOAM successfully. In Fact, I was really excited to use it and test different objects until I realized that the GUI was non-existent and the recommended GUI called ParaView was absolutely horrible.

So that evening I got soo pissed, that I hopped on blender and decided to make my own CFD. It literally took me just 3 hours to make . I had to tweak certain things to make it fit real-world parameters such as gravity, drag, stickiness, and friction to make it function optimally.

Now like I said this will be open source and you can find the link to the github page below. I have made the particles (wind) change color depending on the speed it is moving at . If the particles are moving very slow they turn red, if they appear to be accelerating with little resistance they turn green and if there is no resistance it turns blue. This is why you can see at the initial contact point the particles turn red at the front of the car. The red particles help us identify where we should make the car more streamlined.

I have explained the working of the software in the video below:

Wind Tunnel Testing | Project Sierra Log#2

Image
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...

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...
