Pulsation in fluid systems...Is it steady-state or is it transient? Well, it is both. Kind of. Pulsation causes periodic transients that are regular in nature and thus considered steady-state. It can be called "steady-state pulsation".
I am not a political commentator. But anyone not living in a cave has to admit that the past year of American politics was just plain wacky. For those of you for whom English is not your first language, "wacky" is a word that basically means (by my personal definition) "strange, highly unusual and a bit crazy". Which also applies to Donald Trump.
Yesterday was the 75th anniversary of the Japanese attack on Pearl Harbor which catapulted the United States into World War II. For Americans, there was no way to miss the abundant news coverage and the stories of vets who were there that day and are still alive today to share their experiences. As I read about and watched some of the ceremonies and news it got me thinking about the astounding progress humankind made in the 20th century in the field of aviation.
Twenty years ago today I was working desperately on putting the finishing touches on AFT Impulse 1.0. At the time, AFT was a pioneer in every sense of the word. AFT was the first and only company developing visual, drag-and-drop pipe flow modeling software for Microsoft Windows. And AFT Impulse was set to become the world's first visual waterhammer software for Windows. We already had orders for AFT Impulse before it was complete, such was the demand!
A little over 30 years ago I made a mistake. At the time I was a busy undergraduate student in mechanical engineering in California. Some students put together an official weekend trip for ME students to the Hoover Dam that included a special tour of the dam geared towards engineers and engineering students. I remember having tons of homework to do and decided not to go on the weekend trip. That was a mistake and I have regretted it ever since.
This week I was in Las Vegas at the 2016 MINExpo. AFT had a booth at the show and I hoped to publish this during the show and call it a "live" report. Alas I did not get it completed and the show ended yesterday. Hence it is "almost" live.
Last month my wife and I visited the Smithsonian Museum of Natural History in Washington, D.C. While there we saw an inspiring IMAX movie on the American National Parks. I have visited many of these parks and, living in the beautiful American state of Colorado, I have a great appreciation for the importance of preserving natural beauty and the environment. This month the American National Park Service celebrates it's 100th anniversary.
