The thermal-Hydraulics lab of Prof Jacopo Buongiorno, Dr Tom McKrell and Dr. Lin-wen Hu
The thermal-hydraulics lab supports the development of nanofluids for enhanced heat transfer in nuclear and conventional systems, and the study of fundamental boiling phenomena. The lab is equipped with state-of-the-art instrumentation for measurement of thermo-physical properties such as thermal conductivity, surface tension and viscosity, and various flow loops for characterizing convective heat transfer and fluid dynamics behavior, both in single-phase and two-phase flow. A particularly interesting facility uses infra-red thermometry, high-speed imaging and a double-sensor optical probe to obtain detailed and fundamental time- and space-resolved data on pool boiling heat transfer, specifically bubble departure diameter and frequency, growth and wait times, nucleation site density and near-wall void fraction. These data can be used to inform and validate models of boiling heat transfer and Critical Heat Flux.
