Evans Goodling? An engineer? Who is that? Until last month I had almost no idea. The ASME 2022 PVP conference in Las Vegas last month changed that. There I met someone who knows Goodling personally and worked with him in ASME for many years. He gave me some background on how Goodling came up with his steam hammer load prediction method. Which is wh...
Air compressors, they are a machine that everyone has interacted with in their life time. Whether it is in the garage, at the gas station, or in a manufacturing environment compressed air is everywhere. Compressed air is one of the most widely used utilities out there, but also one of the most expensive utilities out there. The key to is to make su...
As if we all need something else to worry about, right? But I am afraid it is true. The concern stems from how fast steam acoustic waves steepen as they transmit through a system. This steepening causes transient forces on the steam piping much higher than conventional methods predict. When I was beta testing AFT's latest software product, AFT xStr...
AFT strives to make our interface intuitive and user-friendly, but we know that pipe flow modeling can be complex. That's why the AFT team have worked to put together the AFT documentation portal, a new centralized place to find all of our help resources for AFT Fathom, AFT Arrow, AFT Impulse, and AFT xStream. Here's a quick summary of what you can...
Be forewarned that today I am going into full on geek mode and talk about equations for transient compressible flow. These equations are in the form of hyperbolic partial differential equations (PDEs'). If that did not scare you away yet, then you may be as much of a geek as I am! With some fancy mathematics, three PDE's can be converted into six o...
In the modern world there are many things we take for granted – especially in first-world countries. Among them are the reliable availability of water and electricity. To our homes. To our workplaces. Just about everywhere. Engineers also take things for granted. One of those is reliable data on the properties of steam and water. But it was not alw...
Let's face it, specifying every pipe size, length, elevation, pump curve and component loss in a hydraulic model can be tedious. While essential to fully defining a system, often there is avoidable redundancy during model specification. The Global Edit feature helps to ease this tedium and redundant specification by mass updating overlapping parame...
