[Notice] Introduction about the "Mechanical Engineering Research" Course

mpffcl — Thu, 10 Jul 2025 12:50:09 +0000

Dear Students, We are now recruiting students for the course "Mechanical Engineering Research" offered in the Fall 2025 semester. Fluid mechanics is, unfortunately, one of the most challenging subjects for undergraduate students majoring in mechanical engineering, both in Korea and abroad. However, the theories covered in undergraduate fluid mechanics courses have been rigorously verified over decades or even centuries. Among these, only the most intuitive and easily observable fluid flow phenomena in real life have been selected and included in your textbooks. Many students have kept their interest away from fluid mechanics due to a lack of fundamental knowledge in college-level mathematics and physics. To address this issue, the Mechanical Engineering Research course (lectured by Prof. Jae-Sung Kwon) in Fall 2025 aims to provide students with the opportunity to explore fluid flow phenomena through computational fluid dynamics (CFD) or experimental methods, focusing on the following topics.

(Microfluidics) Particle separation technique using inertial microfluidics
(Experimental Fluid Mechanics) Automated measurement and data collection of flow rate, flow velocity, pressure, and temperature in pipe flow system using Lab-View program

We hope that this course will serve as a valuable opportunity to spark undergraduate students' interest in fluid mechanics. We look forward to your participation and encourage you to register. Sincerely, Prof. Jae-Sung Kwon =================================================== 안녕하세요, 여러분. 2025학년 2학기부터 시작되는 "기계공학연구" 과목을 수강할 학생들을 모집합니다. 유체역학은 아쉽게도 기계공학을 전공하는 국내외 학부생들이 가장 힘들어하는 전공 과목 중 하나입니다. 하지만 학부생들이 배우는 유체역학의 내용들은 이미 짧게는 수십년, 길게는 수백년 전부터 수많은 검증을 통해 자리잡은 확고한 이론들입니다. 그 중에서도 실생활에서 자주 관찰되는 유동현상들 위주로 이해가 쉽고 직관적인 것들만 발췌하여 여러분들의 교과서에 실어놓은 것입니다. 많은 학생들이 대학수학 및 물리에 대한 배경지식이 부족하여 유체역학에 대한 흥미를 갖지 못하는 경우를 많이 봤습니다. 이러한 문제점을 극복하기 위하여 2025학년도 2학기에 개설되는 기계공학연구(강의: 권재성 교수)에서는, 수강생들에게 다음의 주제들을 통해 유체유동현상을 CFD 또는 실험을 통해 탐구하는 기회를 부여할 계획입니다.

(미세유체역학) 관성 미세유체역학(inertial microfluidics)을 이용한 입자 분리 기술
(실험유체역학) 유체유동 시스템 내 유량, 유속, 압력, 온도의 Lab-View프로그램 기반 측정 및 데이터 수집

"기계공학연구"가 유체역학에 대한 학부생들의 관심을 환기시킬 수 있는 좋은 기회가 되길 희망합니다. 학생들의 많은 관심과 수강신청 바랍니다. 권 재 성 교수
