A-State Closing Early Today Due to Severe Weather Forecasts

The National Weather Service is forecasting a particularly dangerous severe weather event to move into the A-State campus area this afternoon, followed by historic rainfall amounts as we approach the weekend.  A-State will close today at 1 p.m. so that our students and employees can make arrangements to ride out the storms safely. 

The Office of Emergency Management has created a Linktree (https://linktr.ee/AStateSevereWx) with valuable resources for severe weather.  It includes links to the A-State Alert sign-up form, weather news sources, and shelter locations on campus and throughout Craighead County.

Provost's Inclement Weather Policy
A-State reminds all students that if they believe it is unsafe to attend class, please consult the Provost’s Inclement Weather Policy as it relates to classes, especially for our commuter students.

Helpful reminders for severe weather at A-State:

  • Stay weather-aware. Make sure you have a weather app on your phone with the appropriate notifications enabled.  A-State also sends text alerts when the NWS issues a weather warning for the campus area.  Visit the my.AState portal to sign up for our emergency text message system.

  • Have a plan for shelter. The Reng Student Union is our designated storm shelter on campus.  If you are unable to get to the union, find an interior space, free from windows, on the bottom level of your building.

  • Avoid floodwaters. Remember, it is never safe to swim in floodwater due to hidden dangers and contamination. In addition, do not attempt to drive through floodwater.  If you see water finding its way into a campus building or other water issues, please report it to your RA, Building Liaison, or Facilities Management at (870) 972-2066.  For after-hours reports, call UPD at (870) 972-2093.

Park Attracts NSF Grant for Heat Reduction Research in Electronics

10/17/2022

JONESBORO – An assistant professor of mechanical engineering at Arkansas State University is pursuing research with NASA’s Johnson Space Center into how to more effectively reduce heat build-up in electronic systems.

The grant proposal from Dr. Jeongmoon (Josh) Park was approved by the National Science Foundation’s RII Track-4: Fellows Advancing Science and Technology (FAST) program for $174,864.

Before joining the College of Engineering and Computer Science faculty in 2021, Park earned his Ph.D. at Texas A&M, his master’s at Purdue, and bachelor’s at the Korea Aerospace University.

He noted the rapid development of technology has resulted in higher performance and smaller size in electronics. However, with increased circuit density and faster operating frequency, more heat is dissipated and needs to be removed.

Success of this project will lead to thermal performance enhancement of cold plates, thereby reducing equipment size and weight, and saving energy.

“Traditional heat removal systems employing a heat sink and fan often become insufficient for modern electronics to maintain within the operating temperature,” he explained in his grant proposal. “Therefore, this research is driven by the need to develop an advanced thermal management system to remove the dissipated heat sufficiently and maintain the electronics below the operating temperature, for better performance and higher reliability.”

In collaboration with the NASA Johnson Space Center, he will design and develop an advanced cold plate heat exchanger that can remove heat more efficiently and effectively by using vortex generators, an aerodynamic element, especially for electronics in manned spacecraft.

Cold plates have liquid coolant flow passages bounded by metallic walls. The use of vortex generators in the flow passages has great potential to enhance heat transfer, Park continued.

“When better liquid cooling in cold plates is achieved, it can lead to significant energy savings as well as reduced equipment size and weight. Eventually, this research can support the design, development, and implementation of the next generation of thermal management systems for electronics in spacecraft applications.”
