Vertical-Axis Wind Turbines Promise Higher Efficiency - ASME
2021年9月8日 · A single vertical turbine has an efficiency in the range of 35 to 40 percent (though vertical turbine researchers are sure that number will soon reach 50 as well). But, as Tzanakis and Hansen demonstrated in a paper published in Renewable Energy in June 2021, when working together—and arranged properly—vertical-axis turbines have the ...
Vertical-Axis Wind Turbines: Time for a Comeback? - ASME
2012年8月14日 · Test, in a wind tunnel and combined wind-wave tank, a proof-of-concept subscale, deep-water floating offshore wind-turbine generator employing a VAWT rotor; Sandia National Laboratories is undertaking a project to test the feasibility of vertical-axis wind turbine (VAWT) architecture for large-scale deployment in the offshore environment.
Schools and Flocks Inspire Wind Turbine Design - ASME
2017年10月26日 · In those cases, even though a turbine might be farther downwind from an upstream turbine, the downwind turbine can actually produce more power than the upstream turbine by taking advantage of those flow acceleration effects. So that local acceleration of the flow is one distinction between the vertical axis and the conventional horizontal.”
4 Ways to Make Wind Turbines Safe for Birds and Bats
2019年10月30日 · One downside to wind power’s success, however, is its impact to wildlife. Birds and bats in particular can be killed by turbine blades. The Audubon Society estimates wind turbines kill up to 328,000 birds per year in North America, a number expected to grow as more wind farms are built.
ASMEA178CSAB448-Standard for Wind Turbine Tower Elevators
This standard applies to elevators permanently installed in a wind turbine tower to provide vertical transportation of authorized personnel and their tools and equipment only. Such elevators are typically subjected to extreme temperatures, humidity variations, and substantial horizontal motions. Table of Contents

Eiffel Tower Goes Green - ASME
2015年8月5日 · While the result is clearly 21st century, the actual installation of two vertical axis wind turbines set to produce 10,000 kilowatts hours of electricity per year (enough to power the commercial areas of the tower's first floor), was done the old-fashioned way, using ropes, winches, and pulleys. A highly skilled team of rope workers were ...
Winterizing Texas’s wind turbines remains a question - ASME
2022年1月12日 · More for You: Vertical-Axis Wind Turbines Work Well Together Winterized wind turbines can operate in temperatures that dip as low as 30 degrees below zero Fahrenheit, according to the Canadian government. While no one expects Texas to turn into the Arctic, wind farms in southern states shouldn’t wait to winterize, Webber noted.
Growth Spurt for Hybrid Renewable Energy Systems - ASME
2013年8月28日 · A system installed at a coastal location in China for the Chinese Navy to power a communication tower consisting of an off-grid 4K vertical axis wind turbine combined with 2 kilowatts of solar is saving the Navy approximately $30,000 a year.
Tomorrow’s Taller Turbine Towers - ASME
2016年9月23日 · With those restrictions placed on them, the wind-turbine towers can’t reach more than 262 feet, or 80 meters. Yet, while the U.S. installed wind energy capacity has grown by 31 percent over the past five years, the wind industry has mainly introduced bigger turbines and longer blades to help harvest more energy.
