Abstract

The thermal fluidic system (TFS), a type of two-phase device, has recently attracted significant attention in mechatronic system cooling. The aim of this study is to use magnetic nanofluid (MNF) with magnetohydrodynamics (MHD) to enhance the thermal performance of a miniature TFS. The MNF used for the primary working fluid (WF) can be prepared from fine ferromagnetic particles of iron ferrite using a chemical co-precipitation technique. Based on the design of local electromagnetic fields, a transient Lorentz force can be induced within the MNF-based channel flow and thermal convection in MNF can then be actively enhanced. In this study of a novel TFS, the highest thermal performance showed a 41.82 + 0.01% enhancement. This study not only shows an effective technique for identifying TFS dynamics, but also provides valuable suggestions for cooling system designs using regular heat transportation.
