摘要
为了评价现有的临界热流密度(CHF)流体模化技术,在氟里昂-12热工实验装置上完成了φ202.5圆管CHF实验。在此基础上,用不同的数据源,比较了Ahmad补偿失真模型、鲁钟琪模型、Groeneveld模型和Stevens-Kirby经验比例因子模型的预测精度和适用范围,为复杂流道中的CHF流体模化研究奠定了基础。
CHF experiment is carried out in f202.5 tube on the Freon-12 thermal hydraulic facility in order to assess the CHF Fluid-to-Fluid scaling technique. Based on different databases, the compensated distortion model of Ahmad, Lu Zhongqi model, Groeneveld model and the empirical scaling model of Stevens-Kirby are compared on the aspect of predication precision and applicable range. It is the fundament for the experimental study of CHF Fluid-to-Fluid scaling technique in complex channel.
