Trend in CFD Technology and CFD Case Simulation on Drilling
Journal of The Korean Society for Fluid Power & Construction Equipments, 2012 1. 서 론최근 공학산업이 고도화, 정밀화, 다양화되어 부품과 장치 산업에 대한 정밀 설계 및 최적설계가 요구되고 있다.분야에 관계없이 시스템 및 부품의 설계 시 시간과 비용을 절감하면서 다양한 형태의 설계 결과를 통해 보다 최적화된 제품을 생산하고자 하는 것이 생산성 향상 및 기술고도화를 추구하는 현대 공학의 궁극적인 목표이기도 하다. 이러한 현대 공학의 목표를 달성하기 위해서는 전산설계 및 수치해석 기법이 요구되며 시스템 및 제품설계에 있어 불가결한 부분이 되었다.다양한 수치해석 기법 중 본 논문은 전산유체역학의 소개 및 기술동향, 이를 이용한 연구사례에 대하여 서술되었다.

CFD simulation of flapped rotors [PDF]
The Aeronautical Journal, 2015 AbstractThe use of active trailing edge flaps on rotors may lead to performance benefits as well as noise and vibration reduction. In this work, computational fluid dynamics, using the HMB2 solver, is used to assess the effect of the trailing edge flaps on the whole flight domain of a modern main rotor.
