  • Partnership lends computational support to acclaimed research into polar climate change
    efforts to build up and disseminate greater knowledge about man made climate change This recognition further increases the visibility of this critical global issue and challenges mankind to find ways to live more harmoniously with nature while enhancing the quality of life for everyone said Bromwich an Ohio State University researcher The IPCC does not conduct any research itself rather the panel collaborates with hundreds of scientists from around the world who conduct research on global warming As a senior research scientist at OSU s Byrd Polar Research Center and a professor with the atmospheric sciences program of the department of geography Bromwich works with other research scientists to decipher climate change Because they needed to better simulate the unique weather and climate over the earth s polar regions the research team developed customized computer weather prediction models specifically for use over high latitudes Bromwich and his colleagues use these models for a variety of applications including forecasting weather for the U S Antarctic Program studying the general climates of polar regions and their influences on the world s climates predicting the growth decline of the Greenland and Antarctic Ice Sheets and their impact on sea level and simulating past climates such as the Last Glacial Maximum of about 20 000 years ago to gain perspective on variability of current climate These atmospheric models are based on equations which are solved at thousands of points on a three dimensional grid placed over an area of interest on the globe Bromwich said And these equations need massive computational power to complete By tapping the resources and expertise at the Ohio Supercomputer Center for the past two years we ve had a local partner that enables us to generate model results determine the causes of the simulated changes and store the data

  • Soldiers’ Chances of Surviving Mine Explosion Increase With Improved Seat Design, Research Shows
    of Cincinnati The blast from anti tank mines or improvised explosive devices commonly called IEDs can load the floor of the personnel carriers or other non tank vehicles When this happens shock waves transfer from the floor to the seats to the occupants often with such force that it can crush the occupants and severely injure or kill them Some U S Army vehicles have various forms of protective seating that absorbs some of these acceleration pulses or shock waves this study is part of an effort to update vehicles that do not have such protection as well as refining those that already do Instead of bolting the seat directly to the floor Tabiei designed a seat attached to steel rails encased in aluminum tubes Computer simulations showed that the force of a mine blast now moves from the floor to the tubes crushing them in the process Ultimately the final design reduces the amount of force being transferred to passengers inside the vehicle to well within levels the body can withstand He first created mathematical formulas that represent different aspects of the vehicle Next he used special software LS DYNA 3D to create a computer model of the vehicle including seats tires and human prototypes and translate the formulas into a simulation That s when he turned to the high performance computing resources at the Ohio Supercomputer Center in Columbus Tabiei perfected the simulation by running his data intensive model more than 500 times on the Ohio Supercomputer Center s Intel Itanium2 computer cluster Once Tabiei ensured the model accurately simulated the force and injuries caused by an explosive force he could reliably test and modify the designs for energy absorbing seats without having to build and evaluate multiple individual prototypes Many fatalities happen because of the acceleration pulses

  • Building Better Aircraft Engines, Hydrogen Fuel-Cell Race Cars
    to make those predictions so we can bypass the need for very expensive and sometimes impossible experiments says Ghosh professor of mechanical engineering and materials science and engineering Our computational simulations are like virtual experiments to simulate the real behavior and to incorporate the findings into design He would not be able to conduct such complex research without the aid of high performance computing facilities but he doesn t have to go far to find such resources The Ohio Supercomputer Center on Ohio State s West Campus allows him to examine and predict reliability from the very small scale of the materials used in parts all the way up to the overall structure For example he has examined aerospace systems for the Air Force thermal barrier coatings such as those on space shuttles for NASA aluminum sheeting for ALCOA aluminum castings for Ford and nanocomposites for drug delivery systems Just one example of results His findings of better systems of aluminum rolling resulted in approximately 150 million in annual energy savings for ALCOA Hundreds of Ohio researchers many of whom like Ghosh are Ohio State faculty take advantage of the Ohio Supercomputer Center which has its 20th anniversary this year This is a statewide resource available for the higher education community and the industrial community to do complex calculations to advance science economic development and the development of products says center director Stanley Ahalt an Ohio State professor of electrical and computer engineering The center also is a resource for engineering students Kimberly Stevens a senior majoring in aeronautical and astronautical engineering used software there to simulate the shape of the Buckeye Bullet 2 a high performance hydrogen fuel cell powered race car Using computational fluid dynamics Stevens modeled real world aerodynamics and the Buckeye Bullet team built a model for testing in a Penske wind tunnel We went to the wind tunnel in North Carolina with a really good shape and good idea of what to expect from the wind tunnel testing Stevens says Since the car was already optimized for drag we were able to focus on stability issues She also plans to use the software to help design the cooling system of the car In fact Stevens enjoys computational fluid dynamics so much that she intends to make a career of it The experience offered by the Ohio Supercomputer Center has lead to two really cool jobs for me a computational fluid dynamics co op position with Honda Research and Development and a computational fluid dynamics research job for the Department of Aerospace Engineering here at Ohio State she says noting that she ll start a master s degree in 2008 Early this year the state granted the center more than 4 4 million for an upgrade to be completed this summer Ashok Krishnamurthy Ohio Supercomputer Center director of research and an associate professor of electrical and computer engineering says faculty and students across the state can access the center s systems and network and researchers there

  • Tracking Amazon flood patterns
    Report 2007 Research Report Computational Science Engineering Applications Research Tracking Amazon flood patterns Principal Investigator Doug Alsdorf Ph D The Ohio State University Funding Sources Petrobras S A Piatam Project NASA and the UK Royal Society Using the high performance computing and support resources of the Ohio Supercomputer Center Ohio State University Earth scientist Doug Alsdorf Ph D and his colleagues successfully predicted flooding patterns for 5 000 square miles of the central Amazon floodplain This was the first time a hydrodynamic model of this scale was successfully used to resolve complex floodplain flow patterns Until this work hydrologists didn t know much about the Amazon s seasonal floods Almost no data existed on the Amazon s flooding behavior over large areas such as where the waters rise first the elevations or how fast the waters ebb Dr Alsdorf said To understand the hydrological and biogeochemical processes in the ecosystem it was critical to find a way to understand the flood patterns Water level gauges typically register a change in water elevation over time However these are sparsely placed on the Amazon and only in the main channels So the researchers turned to the Shuttle Radar Topography Mission and other satellites for records of floodplain topography water levels and highly accurate water level fluctuations The researchers took the enormous amount of satellite data and simulated water movement through the Amazon floodplains using the computer program LISFLOOD FP At Dr Alsdorf s request OSC researcher Judy Gardiner Ph D adapted the program to run quickly and efficiently on multiple processors of the Center s Cray supercomputer With Judy s help we went from four weeks of compute time on a desktop to less than four days Dr Alsdorf said Because of this we were able to tweak the formulas and do
