【摘要】：以某先進(jìn)壓水堆核電廠汽機(jī)房為研究對象,計(jì)算了汽機(jī)房的散熱量,獲得了各層散熱量分布情況。在構(gòu)建汽機(jī)房幾何結(jié)構(gòu)的基礎(chǔ)上,建立了汽機(jī)房內(nèi)空氣流動與傳熱過程的理論模型并進(jìn)行了數(shù)值計(jì)算,開展了4種通風(fēng)方案情況下的空氣流動與傳熱的模擬研究。依據(jù)模擬所得的室內(nèi)流場情況,采用能量利用系數(shù)等指標(biāo)對4種通風(fēng)方式進(jìn)行了綜合評價(jià)。研究結(jié)果表明:通風(fēng)方案對工作區(qū)平均溫度低于32℃區(qū)域所占比例有較大影響,選用含機(jī)械進(jìn)風(fēng)通風(fēng)方案在降低工作區(qū)溫度方面具有優(yōu)勢。機(jī)械進(jìn)風(fēng)、機(jī)械排風(fēng)的通風(fēng)方案是汽機(jī)房通風(fēng)系統(tǒng)的優(yōu)選方案。
[Abstract]:Taking the steam engine room of an advanced PWR nuclear power plant as the research object, the heat dissipation of the steam engine room is calculated, and the distribution of heat dissipation in each layer is obtained. On the basis of constructing the geometry of steam engine room, the theoretical model of air flow and heat transfer process in steam engine room is established, and the numerical calculation is carried out, and the simulation study of air flow and heat transfer under four ventilation schemes is carried out. According to the simulated indoor flow field, the energy utilization coefficient was used to evaluate the four ventilation modes. The results show that the ventilation scheme has great influence on the proportion of the average temperature of the working area below 32 鈩，
