ABSTRACT

The aim of present work is to investigate the effect of seismic excitation on thermal characteristics of a liquid pool and the submerged heater experimentally. The effect of amplitude and natural frequency of liquid on heater’s thermal performance and thermal stratification of liquid have been investigated. Results emphasize that the pool excitation influences the single-phase convection and subcooled boiling Heat Transfer Coefficient (HTC) significantly. The experimental data generated in the present study would be useful for the CFD model development. Sloshing driven heat transfer mechanism leads to significantly different temperature profile in the pool.

地震激发下水下垂直加热器的瞬态热特性

摘要

本工作的目的是通过实验研究地震激发对液池和浸没式加热器的热特性的影响。研究了液体的振幅和固有频率对加热器热性能和液体热分层的影响。结果强调，池激发显着影响单相对流和过冷沸腾传热系数（HTC）。本研究中产生的实验数据将有助于 CFD 模型的开发。晃动驱动的传热机制导致水池中​​的温度曲线明显不同。
