传统排风罩和气幕上吸罩是两种工作原理不同的局部排风设备。建立了气幕上吸罩流场模型并确定了边界条件,采用数值计算的方法,模拟了气幕上吸罩速度场和温度场。提出把控制点(面)速度作为评价流场控制能力强弱的一个参数,并依此定量比... 传统排风罩和气幕上吸罩是两种工作原理不同的局部排风设备。建立了气幕上吸罩流场模型并确定了边界条件,采用数值计算的方法,模拟了气幕上吸罩速度场和温度场。提出把控制点(面)速度作为评价流场控制能力强弱的一个参数,并依此定量比较了传统上吸罩和气幕上吸罩的控制效果。结果表明:送风射流装置可以把热污染气流控制在较小的范围内;在模拟实验条件下,在控制点达到相同的控制风速时,气幕式上吸罩所需吸气量为传统吸气罩吸气量的77%~86%。 展开更多

During the course of the last years the need for the increase in the electric energy production in Brazil as well as in the rest of the world, has raised the tone of the debate about the environment impact of such production. As a result of these debates, both the several levels of government and some of the NGOs (Non-Governmental Organizations) have commissioned innumerous opinion researches aiming at measuring and evaluating the knowledge and perception of the public in relation of the best non-polluting energy sources. Prior to 2001 these researches would not make any sense in Brazil., however due to that year's drought, the competent authorities were faced with the necessity of developing a plan, the PNE2030 (Piano Nacional de Energia) aiming, among others objectives, at finalizing the construction of the Angra three plants and implementing new nuclear plants in places still to be determined. Allowing for the complexity of the subject, this paper presents a field research conducted from September 28th, 2010 to October 28th, 2010 assessing the current level of perception of the Brazilian population about the nuclear area, in particular of the residents of three cities of Rio de Janeiro. As a result of this work, the authors suggest how the competent authorities should proceed to reach in an efficient manner a greater understanding of the population about the proposed subject, through communication campaigns being both informative and educational. 展开更多
