#flow simulation

November 15th, 2023

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.

Resolution Effects on Ocean Circulation

The Gulf Stream current carries warm, salty water from the Gulf of Mexico northeastward. In the North Atlantic, this water cools and sinks and drifts southwestward, emerging centuries later in the Southern Ocean. Known as the Atlantic Meridional Overturning Circulation (AMOC), this circulation is critical, among other things, to Europe's temperate climate.

hello there! can i ask you what app do you use to draw and what are your favorite brushes if it’s not too much trouble? :D

i used photoshop for a long time. official CC and cracked versions but things got to pricy or kept braking so i switched to Clip Studio Paint. Its a good program all in all i like it but it takes some time getting used to everything. i have this post about what brush i like to use and how LINK but so far i couldn't manage to recreate it in CSP yet and the settings are still a bit to new to me. but i like the SOL brush so far the most. probably uhm... idk just for understanding. i use an intuous 4 tablet. its like... old but works like one the first day. so nothing fancy with a screen in it or something.

The thing with the Byler twist - and it is a twist, even if we’ve predicted it - is that all that the general audience really needs to be on board is to realize that all of Mike’s behavior will have remained in character. No sudden change or confusion to accommodate this fan service ship. Even if you didn’t see it coming, it is very consistent with his behavior over the seasons.

That’s all you really need for a good twist. Not predictability but rewatchability. Does it makes sense? It doesn’t matter if it was built up. Because this isn’t a slow burn. It’s an “it was under my nose the whole time” subversion. Yes, it’s been built up from the start but that’s the part about being under your nose the whole time. Some people will have caught it some won’t, but ultimately, the fact that Mike’s behavior won’t change is what will make people see it.

Because the general audience is, by definition, not actively fighting the idea. Casual viewers. Character consistency is all that’s needed. Even if it WERE to be fan service, if they were to be able to execute that unplanned plot with great character consistency, props to them, that’s the story now, and I’ll accept it. (Just like I say a non-Byler ending would be totally great if it can maintain character consistency and realistic happy endings within that - I just can’t think of a way it can). 

This has been a long way of saying.

Mike and Will getting together will not feel out of character or like an adjustment or accommodation to this “new” storyline. And that’s really all that’s ever needed for a twist or subversion to work. It doesn’t have to be foreshadowed or predictable. It just needs to make sense. And as long as that’s true, no general audience member will fight it.

Venus Flower Basket Sponges

Venus flower basket sponges have an elaborate, vase-like skeleton pocked with holes that allow water to pass through the organism. A recent numerical study looked at how the sponge's shape deflects incoming (horizontal) ocean currents into a vertical flow the sponge can use to filter out food.

honestly the only difference you need to know about mirror’s edge versus mirror’s edge: catalyst is that in order to play mirror’s edge, i have to dig out my xbox 360, cords and cables, hook it up, hit it a few times to get it running, and hope the disc still reads. and to play catalyst, i just pull it up on my ps4. and i still feel the urge to replay mirror’s edge a dozen times a year while i haven’t touched catalyst since i finished it.
