Biography

Born in Southern California, I moved to Evanston, IL to attend Northwestern University for a B.S. in Mechanical Engineering. As an undergraduate, I worked with Engineers for a Sustainable World in small-scale wind energy projects that combined my interests in sustainable development and technical design. After graduation, I entered into an Engineering Development Program with Siemens Energy where I completed a rotation in large-scale wind and worked in gas turbine casings design for the following 3.5 years.

Abstract

Despite the evolution of wind turbines, the way in which in-situ meteorological information is obtained has not evolved much. Wind vane and cup anemometers, installed at the turbines nacelle, right behind the blades, are still used. This near-blade monitoring does not provide any time to readjust the profile of the wind turbine, and subjects the blades and structure to wind gusts and extreme incoming wind conditions. A solution is to install wind lidar devices on the turbine’s nacelle. This technique is currently under development as an alternative to traditional in-situ wind anemometry because it can measure the wind vector at substantial distances upwind. However, most used wind lidar systems are optimized for measuring within a fixed upwind range, but at what upwind distance should they interrogate the atmosphere? This work uses Large Eddy Simulations to create a realistic atmospheric flow to evaluate optimal scanning distances to learn about the incoming turbulence as a function of wind farm configuration and atmospheric stratification. A correlation model, based on a modified truncated normal distribution, has also been developed, which could be implemented within the feed-forward collective pitch control of the turbine, allowing for improved wind turbine readjustments.

Regardless of the evolution of wind energy harvesting, the way in which turbines obtain in-situ meteorological information remains the same – i.e. using traditional wind vanes and cup anemometers installed at the turbine’s nacelle, right behind the blades. As a result, misalignment with the mean wind vector is common and energy losses up to 4.6% can be experienced as well as increases in loading and structural fatigue. A solution for the near-blade monitoring is to install wind LIDAR devices on the turbines’ nacelle. This technique is currently under development as an alternative to traditional in-situ wind anemometry because it can measure the wind vector at substantial distances upwind. But at what upwind distance should they interrogate the atmosphere? and, what is the optimal average time in which to learn about the incoming flow conditions? This work simulates wind fields approaching isolated wind turbines and wind turbine arrays within large wind farms using Large Eddy Simulations. The goal is to investigate the existence of an optimal upstream scanning distance and average time for wind turbines to measure the incoming wind conditions under different ambient atmospheric conditions. Results reveal no significant differences when measuring the incoming wind vector at different upstream distances, regardless of the atmospheric stratification. Within this framework a 30 min readjustment period is observed to perform the best.

Why Your Life Is Not A Journey

u0824780 — Sat, 24 Sep 2016 08:40:10 +0000

The existence, the physical universe is basically playful. There is no necessity for it whatsoever. Is isn’t going anywhere… that is to say, it doesn’t have some destination that it ought to arrive at. But it is best understood with analogy with music. Because music, as an art form, is essentially playful. We say you play the piano, you don’t work the piano. Why? Music differs from, say, travel. When you travel you are trying to get somewhere. In music, although, one doesn’t make the end of the composition, the point of the composition. If that was so, the best conductors would be those who played fastest; and there would be composers who wrote only finales. People would go to a concert just to hear one crackling chord, because that’s the end! Same way with dancing. You don’t aim at a particular spot in the room, because that’s where you will arrive. The whole point of dancing is the dance. Now, but we don’t see that as something brought by our education into our everyday conduct. We’ve got a system of schooling which gives a completely different impression. It’s all graded, and what we do is put the child into the corridor of this grade system with a kind of, “Come on, kitty, kitty, kitty,” and you go to kindergarten and that’s a great thing because when you finish that you get into first grade… and then come on first grade leads to second grade and so on and then you get out of grade school you got high school and it’s revving up, the thing is coming, then you’re going to go to college… And then graduate school, and when you’re through with graduate school, you go out to join the world. Then you get into some racket where you’re selling insurance, and they’ve got that quota to make, and you’re going to make that. And all the time that “thing” is coming. It’s coming, it’s coming. That great “thing”. The success you’re working for. Then when you wake up one day about 40 years old and you say… “My god, I’ve arrived….. I’m there.” And you don’t feel very different from what you’ve always felt. Look at the people who live to retire, to put those savings away. And then when they are 65, they don’t have any energy left, and they go and rotten in some senior citizens community. Because we simply cheated ourselves the whole way down the line. We thought to life by analogy with a journey, with a pilgrimage, which had a serious purpose at the end. And the thing was to get to that end. Success, or whatever it is, or maybe heaven after you’re dead. But, we missed the point the whole way along. It was a musical thing, and you were supposed to sing, or to dance, while the music was being played.
