2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.
The atmosphere can be divided vertically into four m
remove large debris such as sticks, leaves, trash and other large particles
water stored in reservoirs for periods between a few days and many months to allow natural biological purification to take place
salts are treated with soda-ash (Na2CO3) to precipitate CaCO3 out utilizing the common-ion effect
chlorinated to minimize the growth of fouling organisms on the pipe-work and tanks
Wetting(습윤) : 기체/고체의 계면이 액체/고체의 계면으로 대체되는 것
σs : 기체/고체의 표면(계면)장력
σi : 액체/고체의 계면장력
A : 습윤장력(wetting tension)
A>0 이면 σs>σi 가 되고, 큰 계면장력을 가진 고체표면을 액체/고체계면이 덮게 되며 젖음 현상이 넓게 퍼짐

. 결정화의 기본 개념
결정화(Crystallization)란 분리기술의 일종으로 액체 혹은 기체의 균일상으로부터 조작을 통하여 고체입자, 즉 결정(Crystal)을 얻는 것을 말한다. 우리주의의 실생활에서 자연발생적으로 결정화 현상을 볼 수 있는 데 이것이 바로 눈(snow)의 경우이며 또한 바닷물을 증발시켜 소금을
of oxidative phosphorylation. So H+ pumps transport protons to extracellular fluid to maintain normal cytoplasmic pH.
Thus, Tumor acidity is a specific tumor biomarker. pHLIP is pH-dependent molecule, so it detects the concentration change of proton. If pH is lower in extracellular surface, this molecule enters into phospholipid bilayer due to transmembrane part containing uncharged Asp by
concentration, 카메라 노출시간, 시간 간격t등은 실험조건 및 사용하는 PIV 계측기법의 종류에 따라 다르게 설정하여야 한다.

(i.e. smaller molecules will diffuse faster than larger molecules).
Transport proceedes via diffusion through a nonporous membranes.
Membranes are highly swollen to reduce diffusive resistence.
Applications
Dialysis is used in varying circumstances such as: when a large pressure difference on the sides of the membrane is impractical, in heat sensitive areas, and when or
