Abstract

In this study, the flow analyses around according to the existence or non- existence of the trailer's deflector and the shapes were carried out. In the absence of a deflector, the kinetic energy of the turbulence behind the container also generates higher kinetic energy in a wider area than in the presence of a deflector, which adversely affects the vehicle's driving performance. As a trailer's wind deflector-free model has unstable flow rates around the trailer and high kinetic energy of turbulence than a model with a deflector, it can be thought that the increase of fuel economy can be expected by installing a deflector in the trailer. By applying the study result on flow analysis near trailer due to shape of wind deflector, this study is seen to be suitable for the aesthetic convergence.

본 연구에서는 트레일러의 디플렉터의 유무 및 그 형상들에 따른 주위의 유동해석을 하였다. 디플렉터가 없는 경우는 디플렉터가 있는 경우보다 컨테이너 뒤로 생기는 난류의 운동에너지도 더 넓은 영역에서 더 높은 운동 에너지가 발생하여 그 항력으로 인하여 차량의 주행성에 나쁜 영향을 미친다. 트레일러의 윈드 디플렉터가 없는 모델은 디플렉터가 있는 모델보다 트레일러 주변 유속이 불안정하고, 난류의 운동에너지도 많이 생겨서, 트레일러에 디플렉터를 설치하므로서 그 연비상승을 기대할 수 있다고 사료된다. 윈드 디플렉터 형상에 따른 트레일러 주위의 유동해석에 대한 연구결과를 적용함으로서, 본 연구가 미적인 융합에 적합된다고 보인다.
