The growth rate and uniformity of Carbon Nano Tubes (CNTs) based on Chemical Vapor Deposition (CVD) technique is investigated by using a numerical model. In this reactor, inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as  carrier gas enters into a horizontal CVD reactor at atmospheric pressure. Based on the gas phase and surface reactions, released carbon...

The paper investigates parallel channel instabilities of natural circulation boiling water reactor. A thermal-hydraulic model is developed to simulate two-phase flow behavior in the natural circulation boiling water reactor (NCBWR) with the incorporation of ex-core components and recirculation loop such as steam separator, down-comer, lower-horizontal section and upper-horizontal section and th...

In Japan Atomic Energy Agency, an innovative sodium cooled fast reactor of 1500MWe class, JSFR, has been investigated on the Fast Reactor Cycle Technology Development project. A compact reactor vessel (R/V) and a column type upper inner structure with a radial slit for an arm of a fuel-handling machine are adopted. These result in increase of the spatial-averaged velocity on the horizontal cros...
