论文摘要
在本文中，我们介绍了使用梯度热通量传感器（GHF）进行热通量测量的发展。 GHFS是由具有各向异性热电特性的人工创建的材料制成的传感器。它的特性，包括小尺寸，健壮性和较低的响应时间，使其成为表征空间限制的几何形状以及恶劣环境条件的热通量的宝贵补充。这使其非常适合研究加压水反应器的蒸汽发生器中的反流凝结。事故期间的反流冷凝器操作模式以及维护条件可以提供明显的被动冷却，从而消除了反应堆芯的残留衰减热，从而防止或至少延迟潜在的核心毫无发现。随着这种新颖的GHF实施，在反流凝结过程中，热通量更深的表征。
In this paper we present the developments in heat flux measurements using gradient heat flux sensors (GHFS). The GHFS is a sensor made of artificially created material with anisotropic thermo-electrical properties. Its properties including small size, robustness and low response time make it a valuable addition for characterizing heat flux in space-limited geometries as well as harsh environmental conditions. This makes it ideal for investigation of reflux condensation in the steam generator tubes of a pressurized water reactor. The reflux condenser mode of operation during accident as well as maintenance conditions can provide a significant passive cooling, removing the residual decay heat from the reactor core, thus preventing or at least delaying potential core uncovery. With this novel implementation of GHFS deeper characterization of heat flux during reflux condensation was achieved.
