#flow simulation

These photos are from the air flow simulation I did yesterday, to find out what impact the wind would have on the structure of the identification buoy. I recorded the animations to make it easier to analyze.

It was fun to do this, I discovered that I can make several different types of fluids, which could be useful in future projects. The article is almost ready, along with the boat and buoy codes.

Here are the charts with results generated from Solidworks:

Generally I don't do this, but I'll put the translation of the analysis I put in the article here, maybe it can help someone.

Although it is not common to carry out engineering tests in this specific context, we chose to conduct an analysis dedicated to aerodynamic conditions, aiming to understand the effect of wind on the structural integrity of the buoy. To carry out this study, we used Solidworks, making use of the fluid simulation system incorporated into the program.

Initially, we modeled the buoy structure, assigning specific materials to each component. Subsequently, we establish the necessary boundary conditions to faithfully simulate the behavior of the structure in real conditions. In the next step, we created surfaces that represent the wind pressure in the region where it impacts the buoy, and defined the area in which the wind pressure would be applied. The application of wind loads and adjustment of analysis settings were carried out using the “Flow Simulation” tool.

This process allowed an accurate representation of the aerodynamic conditions on the buoy structure. Additionally, we adjust relevant parameters for the analysis, ensuring a comprehensive approach.

The simulation execution culminated in the generation of a comprehensive report, documenting the results obtained. The interpretation of these results provided valuable insights into the structure's performance under simulated aerodynamic conditions. This engineering test highlighted the importance of considering aerodynamic conditions when assessing structural integrity.

It is possible to highlight some fundamental reasons for the importance of this analysis, such as the assessment of structural integrity, assessment of operational safety, design optimization, which can result in savings in materials and manufacturing costs.

The Montagem_boia.SLDSAM model was configured with standard parameters, carrying out 57 iterations to achieve convergent results. The mesh was defined with basic dimensions (Nx = 40, Ny = 9, Nz = 17), and boundary conditions were established to represent the fluid environment of interest.

The physical time interval considered was 0 seconds, and the CPU time required for the simulation was also recorded. The simulation results revealed an interesting distribution of fluid properties and flow characteristics. The total number of cells in the mesh was 7626, all occupied by the fluid. Among these, 1106 cells were in direct contact with solids.

The mesh dimensions (X,Y,Z) indicated a significant extension of the model, with minimum and maximum variations in each direction. Analysis of the velocity field revealed a range of [0 m/s; 7,510 m/s], indicating different flow regimes within the simulation domain. The pressure varied between [101294.37 Pa; 101430.23 Pa], with a reference pressure of 101325.00 Pa. The temperature remained relatively constant, with values ​​varying from [293.20 K; 293.21 K]. The fluid density showed a minimum variation, within the range of [1.20 kg/m^3; 1.21 kg/m^3].

There was no consideration of factors such as heat in solids, radiation, porous media and gravity to simplify the model to meet the specific objectives of this simulation. Based on the analysis of the images obtained, the reduction in wind speed becomes visible when facing the structure of the identifying buoy.

Notably, the average wind speed in São Paulo, situated at 25km/h, is insufficient to cause damage to the aforementioned structure or to displace it from its original position. It is also worth noting that, when encountering the obstacle represented by the buoy, the wind flow tends to bypass the structure mostly from above, to the detriment of the sides.

This observation suggests an effective resistance of the buoy to direct wind impact, contributing to its stability and structural robustness. The results clearly indicate that the structure's resistance to wind action is remarkable, since the force exerted by the wind did not reach levels that would compromise the integrity or stability of the configuration.

The solidity of the structure in the face of these conditions suggests that the design presents a robust and adequate response to the expected wind loads.

Stunning Interstellar Turbulence

The space between stars, known as the interstellar medium, may be sparse, but it is far from empty. Gas, dust, and plasma in this region forms compressible magnetized turbulence, with some pockets moving supersonically and others moving slower than sound.  (Image and research credit: J.

I'm a one-man Edge dyad. I'm a Worm of a Scale. I'm a freak. I'm a real creature. I'm what Hersault was hiding from under the floorboards. I speak Cracktrack, Vak, Hyskos, Cunnilingual, and Wolf. There are worms under my skin, but I'm about to do enough Lantern-infused perks to make my eyes bleed light. This shit ain't nothing to me, man.

BLUE LOCK (FARMING SIMULATOR EDITION)

translated synopsis: Ego has given up on producing the world's best striker, but now he stands up to make Japanese agriculture even better than before!? Farmers gathered at the farm "Green Lock" strive to produce 1 in 300th of the quality of branded rice!

Ego, who will become the riceist (megoist)? ⁉️🍚

notes: kome means rice in japanese so basically me+egoist = megoist

Gaming tip: Whenever you play a new game, one of the first things you should do is always try to identify the game’s evil surgery man. Otherwise, you’ll be at a disadvantage. Every game has one, you just have to look hard enough.

Some evil surgery men can be women, as evil surgery man is a gender-neutral term.

Some examples of evil surgery men in games:

Note that not all evil surgery men may be obvious. For example, a common misconception of the video game adaptation of I Have No Mouth and I Must Scream is that the evil surgery man is either Nimdok or AM, but it’s actually Benny.

Good luck!

I'm being incredibly normal about Power Wash Simulator considering the amount of lore it actually has.

Anyway here's my take on the protagonist's vibes.

Strongly considering another Dracula Flow blog themed around Cultist Simulator because that game permanently rewired my brain

Only problem is that I can't think of a Dracula Flow-themed pun for the blog name

So there’s this tank I found on the side of the dumpster in a trusted site.

I want to raise aquatic insects with one of these. What’s the protocol gang? Is this feasible?-it holds water fine. I’m gonna hose it out and disinfect it this week before it touches my car- any advice on disinfecting a tank is welcome.

I’m thinking dytiscids or belostomatids as my top choices for a main big insect and I also want to incorporate some native bog plants. Please share any advice and perhaps even aquatic insect suggestions for a southern USA wetland biome. I’ve only raised damselflies before in a really shit environment, I wanna do this one right.

I'm trying to upload examples of headshot drawings in my Ko-fi, and I realized I don't have much.... Take this as a REQUESTS OPEN signal, ask away :)!!

My court mandated therapist said “You’re going to Hell in real life”. Then they turned off the simulation.

Kolmogorov Turbulence

Turbulent flows are ubiquitous, but they're also mindbogglingly complex: ever-changing in both time and space across length scales both large and small.  (Image credit: C. Amores and M. Graham) Read the full article
