turbulent core. This process is often referred to as "eddy diffusion." The value of the eddy-mass diffusivity will be very much larger than the molecular diffusivity in the turbulent core.
2. Fluid dynamics
- In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid flows past stir bar. This phenomenon is most visible behind large objects in swift-fl
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

(1) CFD의 정의
-1960년대에 들어서면서 컴퓨터의 급속한 발달에 힘입어서 과거에는 이론적으로 해석할 수 없었던 복잡한
Time-Average된 Streamline을 살펴보면, vortex의 모양이 뚜렷이 나타나지 않았다. 3번에서 구한 Reynolds Number(Re)의 값은 000이다. Re가 300과 3x106 사이에서는 Karman Vortex가 일어나는 영역을 넘어 난류(Turbulent)로 넘어감을 의미한다. 원래대로라면 매우 복잡하고 비선형적인 Streamline이 나타나야 하지만, 본 실험에서는
