What is it about?

The main objective of this work is to propose a novel lattice Boltzmann method for the two-phase nanomagnetic fluid under a non-uniform variable magnetic field. The current numerical models are not accurate enough for predicting the flow and heat transfer of nanofluids. Although such as circular cavity is widely employed, the two-phase flow in the previous literature is almost limited to the square cavity system. To our knowledge, the study involving the two-phase LBM on the magnetic nanofluid has rarely been reported.

Why is it important?

Nanofluid could be the proper coolant. It showed great potential in improving the thermal efficiency of engineering equipment. Magnetic fluid (nanomagnetic fluid) is a stable liquid containing dispersed colloidal magnetic nanoparticles. It is widely employed in biological, thermal, and mechanical engineering.


Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. This article also lead to nanofluid heat transfer researchers contacting me and ultimately to a greater involvement in nanofluid heat transfer.
