    Not just self-supporting, but the continuous wriggling of the gyroids accelerates the fluids side to side, causing local hot and cold volumes to convect and mix. That forces mixing and turbulence at the wall and prevents stratification in the fluid. Brilliant!

    In regards to simulated fluid flow. I'd be curious of the oil pressure delta if any from the current to proposed design. With smaller passageways compared to the current design, I imagine you either need to run higher head pressure or it results in lower overall oil pressure. Just a single curiosity I have, seems like a genius part.

    • @darkfur18

      Response from Dr. Andreas Vlahinos: “The pressure drop on tube and shell designs is higher since the fluid needs to travel through a single tube. Gyroids provide several passages and therefore have better pressure-drop performance. Using optimization, within the CAD environment, one can use the unit cell sizes (dx, dy, dz) and the gyroid thickness (t) as design variables to minimize pressure drop and keep temperature less than the requirement. I demonstrate this workflow in my short courses and university classes.”

      This isn't actually a worthwhile application of 3D printing yet. The metalurgy of 3D printed parts is still trash, and that doesn't seem to be changing very quickly. Also, the hidden internal passageways SEEM like a neat benefit, until you realize that it cannot be inspected prior to deployment or as part of routine maintenance. On top of that, the parts still require finish machining for threads and precision surfaces, which negates half of the benefits. Ultimately, these kinds of parts can not currently pass any level of the rigorous scrutiny that they must in order to become an FAA certified component.

You can get good single copies, spend a lot of time refining the surface, checking, testing. But all the same, it's not really worth it and the weight gain is not significant there. For example, when an old aircraft is upgraded with new electronics, it sometimes gets tens and hundreds of kilograms in weight gain, and this is a side effect of modernization. To get the same weight gain due to 3D printing, you need to change a lot of parts, and they will be of dubious strength, these are already big risks and it's not worth it.

    @frilime1710 2 роки тому +52

    I am an engineer and worked around engines a lot, the design reminds me to the common heat exchanger on cars, but the manufacturing process go me thinking. First the tensile strenght. One of the common materials used in heat exchangers is duplex 2205 stainless steel, witch is manufactured by forging, and so achieving the required molecular structure and a smooth surface. Then it is built in into the heat exchanger. The tensile strenght of the Duplexx 2205 is 90ksi compared to AlSiMg witch is around 33ksi. The rough surface finish is something that is commonly not desireable in contact with fluids, witch means higher pressure especially early when the fluids are cold. Is there a technology avaibe witch allows similar structures, but with smoother finish and with a higher tensile strenght as the mentioned AlSiMg?

      We put that question to Dr. Vlahinos. He said, “The AM-generated surface roughness provides a higher coefficient of heat transfer. We have not done any testing on fouling. We expect fouling not to be significant as gyroid-flow-domain paths are smooth and we don’t have flow particles hitting flat surfaces or internal cavities. I agree that research needs to be done for various fluids to assess the impact of fouling on gyroid heat exchangers.”

    A heat exchanger demands no fluid contamination on either channel. With laser sintering the finished part is soaked in the bonding metal dust & there is no guaranteed way to dislodge and remove all of it. A solution might be to bring the completed part up to high temperature, just below melting point, then blasting through very hot gasses through each port in sequence. The idea here is to "glaze" the internal surfaces and melt any remaining particles. Destructive testing is needed to find the sweet-spot for this theoretical process.

      @Dark One Which is great when you're deployed out in the field and supply has that part on back order for more than 2 months. 3D printers for this kind of material don't seem to be fast and reliable enough to be a field-ready deployed piece of equipment (yet), and there would be high demand put upon them if more and more parts were made like this. There would still be wait times on turn over for the not only the part to be made but pass whatever NDT process is in place for safety as well.
      Thus something you can break down, clean up, and get working with a wrench and some rags and elbow-grease has it's desirable aspects in many real world situations.

    One of the hardest lessons for engineers to learn is how to design for 3D printing. Designing a part to function as to the design intent while being printable without supports. Also to design for printable material limitations. We are in the stone age as to were this will go. The ability to design and manufacture parts with natural mimicry will bring about a new era of the industrial space age.

    Cool device; however, it has what might actually be an enormous flaw in that it cannot be visually or x-ray inspected for cracks or blockages. One of the critical failure points of a heat exchanger is when the barrier between the different fluids is compromised. For example, in this case, should the barrier between fluids be compromised, you could have fuel diluting the lubricant in the gear housing, producing a gearbox failure (and possibly a helicopter crash as a consequence).
    I'd be very interested to learn of the actual contracts they have actually signed with actual customers, particularly military customers. Personally, I would be a whole lot more confortable going with an inspectable component like the "ancient" tube and shell or gasketed plate heat exchangers.
    Know what this would be perfect for? Homebrewers. If you can make it essentially disposable after a year or so of use.

    Hi, I am or was a Mechanical engineer (not sure which is correct) in charge at one time of maintaining heat exchangers in the electrical generation and oil refining industries. One of the comments interested me talking about the roughness of the exchange surfaces. I was thinking that this roughness may create eddies enabling both liquids to reduce laminar flows ensuring better heat transfer. Please correct me if you disagree because my last experience of exchangers was over 40yrs ago and my college days were way before then. Regards

      It uses curves like a Campaign or old Coke bottle. Ten times more pressure than 'required'. Not difference in pressure, so it's relative to atmospheric. Oil or fuel pressure, ~30psi (a guess), would expect them to be equal on booth sides. Test pressure w/ same potential on both sides, 300psi wouldn't be unreasonable.
      300psi on one side w/o counter pressure, not so much.
