If the thought of doing a fluid flow simulation makes you sweat, worry if you are up to task, try to remember what Navier-Stokes equations were all about, you will rejoice at using AirShaper. A tiny team of five in Antwerp, Belgium has managed to create a flow simulation tool so easy to use that ordinary product engineers can use it.
The next day, you get an email that your solution is available. No ten-thousand dollar program to buy and weeks to learn it. No mesh to create. No technical questions that remind you that you should have listened and retained more from your fluids courses. The model position is verified on the screen, and you can rotate it about the axes if it does not come in properly. Fake streamlines function as a visual aid showing the direction of air flow.
If you are starting to whine about having to wait 24 hours for a canned report, note that the report is over 30 pages, with many images of airflow over your model, tables of data and a well-written narrative that ties it all together you cannot tell it was written in Belgium. How long would it have taken you to produce that?
AirShaper makes meshing completely invisible to the user, taking pains to remove any mention of meshing, mesh size, mesh refinement or adaptive meshing from its interface. Rest assured.
This is real CFD. In addition, AirShaper uses its own techniques to make the mesh adaptive, i. To protect users from themselves, the program limits the speeds of airflow, allowing a maximum of Mach 0.
AirShaper takes pains to explain basics, aware that many who are reading the report or even doing the analysis, may not be fluid flow analysts, or even engineers. Strangely enough, in our test case, a bike rider is shown with a Cd drag coefficient closer to a bus than what is expected of a road biker. Image from AirShaper report. This accuracy was achieved even with the simplest mesh option Concept. AirShaper generates a page report full of streamlines, stagnation plots, 3d model of a plant noise analysis that will make it look like you know your way around CFD.
The report will have enough basic theory that a CEO with no engineering background will understand it. It takes pains to explain what a C d coefficient of drag is in general and how your particular C d relates to objects anyone can identify buses and buildings. AirShaper may have no equal in ease of use among CFD programs. Autodesk Force Effect Flow, which was simpler you could upload a photo, it was only 2D has been discontinued along with all its Force Effect products.
To find out how a small startup can succeed in creating such an easy-to-use CFD program, when the main simulation vendors have only managed to keep it complicated, as well as to find out what is behind the software, we tracked AirShaper Founder and CEO Wouter Remmerie to his home in Antwerp. He called us after he had put his other baby to bed. It is customary for race cars to use airflow for vertical forces downward force from airfoils to increase cornering speed and prevent lift-offbut lateral flow was a first.
Wouter received a patent for it. But despite nibble from both Ferrari and Toyota, neither company took the idea to the racetrack. Air passages required for significant lateral forces take up too much of the width of the car, they said, and the Aquilo was abandoned, according to Wouter.Early in the design process, our designers easily simulate airflow, heat transfer, and fluid forces that are critical to the success of the design of the oven, allowing us to:.

However, as I more recently evaluated CFD software and its integration graphical interfaces, I came to realize its power not only in flow, but also in thermal analysis, which was my main area of interest at the time.
We will start with a simple model of water flow in a pipe. It is a ft horizontal length of 4-in-diameter pipe. Figure 1. Solid model of pipe geometry. Figure 1 shows a simple solid model of a hollow cylinder to represent our pipe. The next step is to bring this model to the flow environment.SolidWorks Flow Simulation - Transient Manifold Airflow
The easiest way of doing this is to use the Flow Simulation Wizard. Figure 2. Flow Simulation menu ribbon. Figure 3. Flow Simulation Wizard dialog box. Conveniently, we can mix and match units. We will continue with the default IPS units. Figure 4. Unit System Wizard dialog box.
The next dialog is the analysis type, as shown in Figure 5. The type of analysis can usually be determined intuitively. Internal flow is bound by a solid at the flow outer boundary. Our current model is internal and the fluid is bound by the pipe walls.
An external flow example would be airflow over an airplane wing. Figure 5. Selecting the analysis type.May 16,Simple airflow simulator? Hello all, Is there a straightforward 2D flow simulation software out there that would let me test some ideas for a home built wind turbine? I'm not looking for aerospace engineering software that does supersonic flows and so on. Just a flow simulator that would let me input an arbitrary shape like a 2D airfoil section and visualize how air would flow around it at regular wind speeds.
I've found Java applets that do this for airfoil shapes but nothing so far that lets you input an arbitrarily shaped section instead of a 'classic' airfoil shape. If anybody knows of such a tool for Windows please point me in the right direction. Regards, WT. May 16,Re: Simple airflow simulator? You can use this website. I hope this helps. Something like this but with the ability to simulate an arbitrary shape not just a "wing" section.
Have you considered a panel method? Find our more. May 17,Re: Simple airflow simulator?
May 27,Re: Simple airflow simulator? The accuracy, however, is controlled by the image resolution, and the output is just a movie of the flow. Anyway, you may play with it and see if it of any use for you. Regards Sergei. June 6,udroi cvykdxw. Thread Tools. BB code is On.
SOLIDWORKS Flow Simulation
Smilies are On.Easy to use, Flow Illustrator enables the visitor to make their own fluid flow simulation videos that can be used for educational purposes, presentations and recreation. The Gallery contains ready-to-use videos, images, and templates.
The video duration, speed, and other parameters can also be specified. This level of flexibility and efficiency is made possible by an original fast algorithm for flow calculations, specially designed for this purpose. If this is your first visit, read what it does on this page.
Then have a look at the videos in Gallery section, to see what you can get. You can also use in the same way the images from our Sample Images libraryand your own images. Have fun! Make your own simulation video with Flow Illustrator! Flow Illustrator - A simple to use online flow simulation tool.
Make your flow simulation! Flow Illustrator creates a video showing the fluid flow air, water, etc. This online simulation tool is very easy to use, because the shape of the object can be communicated to the server simply by uploading the picture of the object. You can even make a video of a flow past yourself: edit a selfie slightly and use this website. The Gallery section contains example videos, where you can quickly see what the result can be like. Make Video section does just that: makes a video for you.
For more information about the available variables look at the parameters to consider page. First, prepare a picture, as a bitmap, that is. Flow Illustrator will assume that pure white area of the bitmap is the flow region and any coloured region is the body, these are used to tell the simulation software where to put the flow.
Use Paint or a similar application to erase those parts of the picture that should be filled with flowing fluid. Upload it from the Make Video section and receive the video ID. Wait a little and download the video. Look at the User guide.
The video will show your object surrounded by fluid, which is suddenly brought into motion with a constant speed. Small white particles, like snowflakes, will randomly appear out of thin air, follow the fluid motion, and then melt.
Some of the fluid will be painted with colours reflecting the rotation velocity vorticity divided by 2 of fluid particles. This trick is widely used in flow visualisations. Together, the snowflakes and the vorticity field give a good idea of the fluid motion.
Read more on what to expect from your simulation. Our server transforms the picture into numbers suitable for input to a code, a Navier-Stokes solver, which, by stepping in time, solves the equations governing the flow past the object. It then converts the numerical solution back into a graphical form and composes the frames into a video. Flow Illustrator is optimised for speed and robustness, with accuracy being traded in.
