올해 가스터빈 심포지엄은 여수 소노캄 리조트에서 개최되었습니다.

첨단 항공 엔진을 중심으로 가스터빈 산업이 주목을 받으면서 심포지엄도 성대하게 진행이 되었습니다.

올해 가스터빈 심포지엄에서는 마이크로 가스터빈 경진대회가 함께 진행이 되었습니다. 작년에 류호영 학생이 은상을 수상했는데 올해 우리 실험실에서는 양류민 학생이 연소 관련 주제로 출품을 해서 좋은 평가를 받았지만 아쉽게 수상은 하지 못했습니다.

국민대에서는 김태호 교수님 지도 학생들이 우수상을 수상하였습니다.

저는 조직위원 겸 Film cooling session의 좌장을 맡았습니다. 이번에 우리나라에서도 미국의 Turbo Expo같은 행사가 가능하다는 걸 느끼고 놀라웠습니다.

우리 실험실 출신 노재원 학생(현재 연세대 대학원 재학 중)이 우수 논문상을 수상하였습니다. 축하 드립니다. 

6월 24일에서 26일까지 용평 알펜시아 리조트에서 개최된 대한설비공학회 2026년 하계학술대회에 다녀왔습니다.

이번 학술대회에서는 열교환기 설계의 디지털 전환이라는 제목으로 전문가 강연을 했습니다.

초청강연으로 일본 공기조화 위생공학회 회장님이 현재 일본에서 진행 중인 공기조화 위생공학의 디지털 전환이나 AI관련 연구를 소개해 주셨습니다.

대학원 연구실 및 업체 홍보 부스에 우리 학부의 이현진 교수님이 진행하는 기초연구실 홍보 포스터가 전시되어 있었습니다.

중앙대학교 이성혁 교수님께서 계면 열전달 및 액적 관련 전문가 강연을 해 주셨습니다.

영문 논문집 관련해서 대만 냉난방공조학회와 양해각서를 체결하였는데 현재 학회 회장님인 장영수 교수님께서 서명을 하셨습니다.
