概要

 Nicholas Gaudern from PowerCurve joins to discuss SilentEdge serrations with up to 5 dB noise reduction, Dragon Scale VGs for AEP recovery, and their approach to products that actually perform in the field.

Energy’s brightest innovators. This is the Progress Powering tomorrow. Allen Hall: Nicholas, welcome back to the show. Nicholas Gaudern: Thanks, Allen. Always a pleasure. Allen Hall: Well, there’s a lot of new products coming outta PowerCurve. And PowerCurve is the aerodynamic leader in add-ons and making your turbines perform at higher efficiency with less loss. Uh, so basically taking that standard OEM blade and making it work the way it was intended to work. Nicholas Gaudern: Yes. We Allen Hall: like to Nicholas Gaudern: think so. Yeah. Allen Hall: And there’s a, there’s a lot of new technology that you’ve been working on in the lab that you haven’t been able to explore to the, introduce to the world, so to speak. Yeah. And we’ve seen some of it from the inside of, you know, you’re working behind the scenes or working really hard to get this done, but now that technology has been released to the world, and we’re gonna introduce it today, some new trailing edge. [00:01:00] Components. Yeah. That really, really reduce the noise. But they, they look a little bit odd. Yes. There’s a lot of ADON dams going on with Nicholas Gaudern: Yeah. Allen Hall: With these. So what, what do you call these new trailing edge parts? Nicholas Gaudern: So, so what you have in your hand here? This is the Silence edge, uh, serration. So this is our new trailing Edge Serration products. Now, most people, when they think of training restorations, they are thinking of triangles. Allen Hall: Exactly. Nicholas Gaudern: These Dino tails. Dino Tails, that’s the Siemens, Siemens name for them. Pretty, pretty standard. You see ’em on a lot of turbines now. Sure. And they work, you know, they do do a job. They do a job. They reduce noise. But like with lots of things in, in aerodynamics, there’s lots of different ways that you can solve a problem and some are better than others. So we’ve worked for a long, long time in the wind tunnel, uh, in the CFD simulations, and we’ve come up with this pretty unique shape. We think, Allen Hall: well, the, the, the shape is unique and if you, if you look at it, there’s actually different heights to the, the triangle, so to speak. To mix the air from the pressure and the [00:02:00] suction side to reduce the, the level of noise coming off the blade Nicholas Gaudern: e Exactly. So we have, uh, we have an asymmetry to the part. We have these different tooth lengths. We have, uh, a lot of changes in thickness going on across the part. So it may be a little bit difficult to see on the camera, but these are quite sculpted 3D components. They’re not, they’re not flat stock white triangles. No, no. There’s a lot of thickness detail going on here. We’ve paid a lot of attention to the edges. We’ve paid a lot of attention to these gaps between the teeth as well. So all of this is about trying to figure out what is the best way to reduce noise. And something that not a lot of people will, will admit, but it’s true, is that as an industry we don’t really understand the fundamentals of how serrations work. Allen Hall: It’s a complicated Nicholas Gaudern: problem. It’s a really complicated thing. Problem, yeah. Yes. So trying to simulate it in CFD is an absolute nightmare. The, the mesh sizes required, the physics models required are really, really difficult. So what we found is that you’re probably better off spending [00:03:00] most of your time and money in the wind tunnel. Yes. So, so we go to DTU, they have this wonderful, uh, air acoustic wind tunnel, the pool of core tunnel. It’s one the best tunnels in the industry for doing this kind of work. It Allen Hall: is Nicholas Gaudern: because you can measure acoustics and aerodynamics at the same time. So this allows us to do a lot of very cost effective iteration for this kind of design work. So we know what’s important. You know, we’ve, we’ve studied all the different parameters of serrations lengths, aspect ratios, angles, thicknesses, all this kind of stuff. And it’s about bringing them together into a, into a coherent product. So this is, this is a result of a lot of design of experiments, a lot of ...
