2024년 동계 유체기계학회는제주도의 피닉스 아일랜드에서 개최되었습니다. 실험실에서 권정우, 최용진 학생과 함께 다녀왔습니다.

초청강연은 효성 굿스프링 사장님께서 해 주셨는데 두바이에서 오래 생활을 하셔서 두바이 관련 재밌는 이야기를 들을 수 있었습니다.

우리 실험실이 참여 중인 무인기용 고효율 터빈관련 과제 특별 세션이 있었고 과제 총괄 책임자이신 연세대 조형희 교수님께서 과제 전반에 대해 발표를 해 주셨습니다.

대한설비공학회 2024년 동계학솔대회가 11월 29일 과총회관에서 있었습니다. 올해는 연구년 중인데 석사논문 심사를 위해 일시 귀국하여 학회에 참석했습니다. 초청강연은 가천대 김창섭 교수님께서 해 주셨는데 산업부에 오래 계셨던 분이셨고 에너지 환경 변화에 따른 정부의 고민과 대응과정을 들을 수 있었습니다.

우리 과제 관련해서는 low GWP 냉매에 대한 특별 세션을 구성하였고 장영수 교수님의 사회로 현대, 삼성, LG 등의 대기업에서 low GWP 냉매를 어떻게 적용하고 대응하는 지에 대한 정보를 알 수 있었습니다.

low GWP 냉매 에어컨 과제의 특별세션이 있었습니다. 사회는 기계연의 김동호 박사님께서 맡아 주셨습니다.

국민대 팀에서는 우리 실험실 최용진 학생은 지난 기계학회 때 발표를 하여 이번에는 장영수 교수님 실험실에서 발표를 했습니다.
