OUR MISSION ABOUT US The Turbomachinery Laboratory, a center of the Texas A&M Engineering Experiment Station (TEES) and a member of The Texas A&M University System, makes a vital impact on turbomachinery and related industries through three pathways: RESEARCH Turbo Lab faculty and students team up with industry partners to conduct research into important problems of reliability and performance of turbomachinery through the Turbomachinery Research Consortium (TRC). The TRC is a unique organization of major turbomachinery developers and users who have joined with the Turbo Lab to find answers to important questions through cutting-edge research. In addition to TRC research, the Lab conducts fundamental and applied research through industry- and government-sponsored projects. EDUCATION WORKFORCE DEVELOPMENT The Turbo Lab produces engineers ready to work by offering The Turbo Lab impacts the turbomachinery industry by undergraduate and graduate engineering education through providing a platform for the continuous exchange of Texas A&M’s J. Mike Walker ‘66 Department of Mechanical ideas among working professionals. These platforms Engineering. The Turbomachinery Research Consortium include the annual Turbomachinery & Pump Symposia blends the Turbo Lab’s impact areas of education and (TPS) in Houston, the biennial Asia Turbomachinery & research by teaming graduate students with industry to find Pump Symposium (ATPS) in Southeast Asia, and solutions to real-world problems. Turbo Lab students are various extended short courses held throughout the highly sought after for industry positions upon graduation. year. Ph.D-level graduates also find positions in academia and government research laboratories. 2018 TAMU Turbo Lab Year in Review | 3

“ TPS offers everything one would hope to expect with the cost of shows. Networking, current and potential customer contact, technical and learning sessions, trend observation, helpful staff and most importantly, targeted exposure to the industry resulting in quality leads. The Turbomachinery Show continues to be one [of our] most successful and beneficial platforms for industry exposure…TPS is relevant and the best show in the turbomachinery industry.” ~ Maeve McGoff, Sales & Marketing Coordinator, Cincinnati Gearing Systems 2018 TAMU Turbo Lab Year in Review | 5

Manish Thorat was one of those students. Thorat studied labyrinth seals in the Turbo Lab under former director Dr. Dara Childs before earning his master’s in mechanical engineering in 2010. Thanks to the TRC, he immediately landed a job with Elliott Group upon graduating. Thorat attended the meeting last week as Elliott Group’s representative. “I would say it is better to be on this side of the podium, rather than presenting on the other side,” Thorat said, laughing. “There’s less pressure, and I get to ask the questions now.” Aside from cutting-edge research, Thorat said the greatest aspect of TRC is that it connects students with feedback directly from industry. “When you’re developing a tool, you’re developing it for industry,” Thorat said. “So getting feedback on what specifics are needed is important.

Faculty Features & Honors FORMER TURBO LAB STUDENT, LESLEY WRIGHT, JOINS FACULTY Dr. Lesley Wright joined the Turbo Lab team in August after teaching at Baylor for ten years. She was encouraged by the head of the J. Mike Walker ’66 Department of Mechanical Engineering, Dr. Andreas A. Polycarpou, and distinguished professor, Dr. Je-Chin Han, to apply for the opening. Wright is investigating enhanced convective cooling technology. This includes heat transfer enhancement for gas turbine cooling applications. SAN ANDRÉS RECEIVES INVITE FOR ADJUNCT PROFESSORSHIP IN CHINA Dr. Luis San Andrés, Mast-Childs Chair Professor of Mechanical Engineering, was named an adjunct professor at China’s Xi’an Jiaotong University, a top 10 global institution for mechanical engineering. He will lecture at the university twice a year, mentor graduate students and collaborate with a team of researchers. He plans to spend the Fall 2019 semester at Xi’an Jiaotong University. FORMER TURBO LAB STUDENT RETURNS AS VISITING SCHOLAR FROM SEOUL Dr. Tae Ho Kim, Associate Professor of mechanical engineering at Kookmin University in Seoul, Korea will serve one year as a Visiting Scholar at Texas A&M University in the Turbo Lab. The appointment is a recognition of Dr. Kim’s work in the fields of gas foil bearings and microturbomachinery rotordynamics. Kim received his Ph.D. in mechanical engineering from Texas A&M in 2007. Dr. Luis San Andrés, Mast-Childs Chair professor of Mechanical Engineering will serve as the host professor. 22 | 2018 TAMU Turbo Lab Year in Review
