추가 적립 안내

현재 유체공학실험 뿐만 아니라 대부분의 실험이 마땅한 교재가 없다. 이는 실험장치의 다양성 및 변경에 따른 이유와 대학교마다 각자 보유하고 있는 실험장치가 다르기 때문이라 판단되고 간단히 프린트해서 사용하는 정도가 편했던거 같다.
이에 저자들은 학생들의 수업능력을 향상시키고 강의내용을 정확히 전달하고 학생들과의 소통문제를 해소하기 위한 목적으로 교보재를 사용하던 것을 단행본으로 집필하였다.
본 교재 Ⅰ절에서는 실험에서 가장 중요한 오차 및 이에 대한 불확실도 개념, Excel을 이용한 곡선접합에 대한 내용을, Ⅱ절에서는 전산유체역학(CFD)을 위한 상용코드 중 ANSYS-CFX의 사용방법을. Ⅲ절에서는 장치실험에 대한 실험방법에 대한 내용을 다루었다. 또한 부록에는 보고서를 작성하는 방법과 유체의 성질자료에 대한 것을 언급하였다.
