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
Passive cooling techniques are key technologies.
Because these can drastically improve the safety and reliability of the reactors.
Techniques that increase the natural convection heat transfer rates should be developed.
The heat transfer of turbulent natural convection can be enhanced by the present promoters.
The present promoters redirect the high temperature fluids in the vicinity
1. Topic
This time we are going to research the safety management and improvement in small scale one room construction. According to the current situation we need to reduce our research scope. So we are focusing in the vicinity of Kyunghee Univ. and Hankuk Univ. of Foreign Studies.
2. Problem statement
2-1. Construction’s needs and industrial accident
2-1-1.
New one-room construct
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
