Visualisation of subcooled pool boiling in nanofluids

Fusion Engineering and Design, 2019
Abstract High-performance cooling is of vital importance for the cutting-edge technology of today, from micro-electronic devices to nuclear reactors. Boiling heat transfer is expected to play a critical role for the safe and efficient operation of components exposed to high heat flux in future nuclear fusion reactors.

An experimental investigation of void fraction characteristics of flow boiling in a 5×5 rod bundle channel

Case Studies in Thermal Engineering
Flow boiling in the rod bundle channel is an important phenomenon in nuclear reactors. The local inhomogeneous void fraction distribution in the flow channel will affect the flow and heat transfer in two phase flow.
