Abstract
This paper presents the findings from an experimental investigation on the performance effect of magnetic field when applied to oscillating heat pipes (OHPs) using kerosene with Fe2O3 nanoparticles as the working fluid. Two types of OHPs were used in this investigation: copper surface OHP and glass surface OHP. The temperature distribution and heat transfer rate through the OHPs were monitored and recorded with and without the magnetic field. In addition, the effect of surface condition on heat transfer for the copper and glass OHPs was investigated. The results have shown that the heat transfer performance of the OHPs improved with the addition of nanoparticles. This improvement was greatly enhanced by the application of magnetic field especially at the higher heat load regions and was more superior for the copper OHP with Fe2O3 nanofluid.
