THERMAL-HYDRAULIC SIMULATION AND EVALUATION OF A NATURAL CIRCULATION THERMOSYPHON LOOP FOR A REACTOR CAVITY COOLING SYSTEM OF A HIGH-TEMPERATURE REACTOR

The investigation into a full-scale 27 m high, by 6 m wide, thermosyphon loop.The simulation model is based on a one-dimensional axially-symmetrical control volume approach, where the loop is divided into a series of discreet control volumes.The three conservation equations, namely, mass, momentum and energy, were applied to these control volumes a

Background: This article critically analyses housing inadequacy in South Africa and its ramifications.Aim: The study is Scarf exploratory in nature and used the qualitative methodology.Setting: Key findings suggest that protests, informal settlements, health challenges, shack fires, flooding, violence and criminality, corruption and xenophobic atta

Control of tropical theileriosis, caused by the apicomplexan Theileria annulata, depends on the use of a single drug, buparvaquone, the efficacy of which is Chemistry compromised by the emergence of resistance.The present study was undertaken to improve understanding of the role of mutations conferring buparvaquone resistance in T.annulata, and the

Experimental results show that ratchets may be implemented in semiconductor and chemical systems, bypassing the second law and Toy Furniture opening up huge gains in energy production.This paper summarizes or describes experiments and results on systems that effect demons and ratchets operating in chemical or electrical domains.One creates temperat

Pulls For some time now, researchers from various academic disciplines have been engaged in the study of green guerrilla gardening, a grassroots activity involving the planting of vegetation in public spaces.In essence, they view it as a social movement with the objective of reclaiming control of public space and modifying its functionality.However
