Applied Thermofluids Laboratory
Applied Thermofluids Laboratory
The Applied Thermofluids Laboratory (ATFL) at Purdue conducts basic and applied research in the thermal-fluid sciences: thermodynamics, heat transfer, and fluid mechanics. We study a wide range of research applications, from safety of lithium-ion batteries to dehydration of food products. Students working in this lab will benefit from a highly team-oriented approach to problem solving. Often times, students will work together on research projects in small, highly-functioning teams. Students frequently have the opportunity to present their work to the group for feedback and so that others can gain a sense of the challenges and problem solving methods being used within the lab. To solve the thermal-fluids challenges posed by industry and government sponsors, students will utilize a combination of experimental and computational research methods. Students will strengthen technical skills as well as skills in communication, writing, presenting, data analysis, and interpersonal relationships. Through this approach, students graduating from ATFL will enter their next career as a more well-rounded engineer and technologist.
Research and Teaching
Li-ion batteries produce heat and gas under certain abuse conditions. We study phenomena such as the onset of thermal runaway, the subsequent venting process, and heat transfer from failing cells to their surroundings. In ATFL we conduct research on advanced numerical modeling and simulation techniques to predict the fire risk associated with Li-ion batteries. Experiments, including destructive tests contained in the blast chamber shown at right, are used to parameterize and to validate models.
Engine and Powertrain Technology
Purdue Polytechnic has a new instructional facility, the Powertrain Technology Laboratory, located in the new Gateway building. Students will learn fundamental operating principles of combustion engines, in addition to sustainability topics such as electrification and alternative fuels. The state-of-the-art facility will provide an unparalleled, hands-on-experience for students to run engines used in today's (and tomorrow's) vehicle propulsion systems.
We are grateful to acknowledge our sponsors and partners for their support.
October 20, 2022: We published a paper on impingement heat transfer related to vented gas jets emerging from a failing Li-ion battery. This is the first study of its kind experimentally measuring the impingement heat transfer rates for these jet flows! The paper is available for download for a limited time, here.
