    around wind turbine blades and flapping wings with the goal of predicting how and when they occur where they will go and how strong they are With financial support from the Iowa Power Fund Buchholz is designing a closed loop recirculating wind tunnel to be constructed in one of the IIHR Oakdale Annexes to allow the team to further study these phenomena It s not feasible to build a wind tunnel large enough to study a utility scale wind turbine so Buchholz is designing a scale model Researchers can compensate for the reduction in size by making the turbine turn faster within limits To actually spin fast enough the turbine would approach the speed of sound causing still more complications The wind tunnel model will not yield performance measurements that can be scaled to utility scale turbines but they are expected to go a long way to improve our understanding of the fundamental mechanisms governing real aerodynamic loads Salad Dressing or Science Buchholz says the model study will include the use of particle image velocimetry PIV to visualize the air flow in the wind tunnel A key ingredient in the PIV process is actually more commonly used in salad dressing olive oil The scientists will build an atomizer to generate very small particles of olive oil which follow the flow of air in the wind tunnel A laser sheet will reflect and scatter light off the oil particles allowing researchers to see the particles and track their motion It s inexpensive and very effective Buchholz says A bottle of olive oil will last for several PhD students The long term goal is to improve the accuracy of the aerodynamic design codes to predict wind turbine performance and loads Once we have a good handle on predicting the formation and evolution of the unsteady flow structures or vortices he says then I think we can address the question of how to optimize the blades in a new way After Fossil Fuels What Then Despite their great size utility scale wind turbines are highly engineered and graceful in design with all the precision of a Swiss watch It s quite an elegant piece of machinery Buchholz says Buchholz remains excited by the prospects of wind energy There are challenges ahead and many of them he freely admits But wind turbines offer a clean source of energy in a world where fossil fuels will eventually be used up We can t stop doing things because there are challenges Buchholz says We have to overcome those things and figure out how to do this better Tags EPSCoR Experimental Program to Stimulate Competitive Research James Buchholz National Science Foundation NSF U S Department of Energy UI wind wind Last modified on June 29th 2015 Posted on November 12th 2013 Home About Greetings from the Director Fact Page IIHR at a Glance Where is IIHR Communications History IIHR s Historical Studies History Resources Hans Albert Einstein His Life as a Pioneering Engineer Sustainability at IIHR Evolving

    rope system A carefully calibrated tow wheel connected directly to the radar system measures the distance covered and a wireless transmitter sends all the data to a computer located nearby but off ice The researchers also meticulously guide and track their progress across the ice using a system of straight line markers to ensure that the lines of data are being consistently collected for repeat surveys and that data are collected along lines critical to the 3 D subsurface tunnel map the researchers are developing As the summer progresses they also monitor drainage from the glacier using continuous stream discharge monitoring systems In the fall the team returns to repeat the radar study and compare the results to the spring data to understand the rate of melting and the tunnel evolution within the massive river of ice These data are combined with climate data for the site and area to better understand the overall hydrologic processes at work on the glacier And the news is not good The tunnel system inside is growing at a very rapid rate and causing more melting from the inside out Weirich says It s essentially more like swiss cheese than we thought Unseen Dangers Even though the team does its work during the temperate months there are still plenty of dangers such as slipping into crevasses or vertical meltwater shafts some hundreds of feet deep which descend from the glacier surface Weather can also pose real challenges Sometimes a helicopter delivers the researchers to remote locations on the glacier On one occasion the weather closed in before the helicopter could carry them back to safety so researchers were forced to spend the night on the ice weathering 40 mile per hour winds fortunately with tents thermal sleeping bags a satellite phone and five days food and water The next day brought no break in the weather so the team hiked out temporarily abandoning their equipment Two days later the weather cleared enough to allow the helicopter back in so the team could retrieve their gear Processing the data in the lab to create a 3 D image is a long and laborious process requiring three software programs The team still has more work to complete on the glacier but Weirich says one result is already clear It s melting faster than we thought Tags Alaska Exit Glacier Frank Weirich ground penetrating radar Last modified on June 25th 2015 Posted on November 12th 2013 Home About Greetings from the Director Fact Page IIHR at a Glance Where is IIHR Communications History IIHR s Historical Studies History Resources Hans Albert Einstein His Life as a Pioneering Engineer Sustainability at IIHR Evolving with the Times Intellectual Connections Worldwide IIHR Alumni Worldwide Archives Films by Hunter Rouse Employment Contact IIHR Webcam Education Graduate Program Admission Assistantships and Fellowships Graduate Student Opportunities Undergraduate Opportunities International Perspectives Service Projects Habitat for Humanity s Women Build Project Fluids Lab Meet Our Faculty and Staff Brandon Barquist Talking Shop Pablo Carrica Enjoying
