In the current study, a magnetic-boiling driven heat transport device has been introduced and modeled numerically. The numerical modeling of the problem has been carried out using Eulerian-Eulerian two phase model and control volume technique. The numerical results showed that a flow of magnetic nanofluid can be induced and drove inside a horizontal tube in the existence of magnetic field (MF) which is due to variations made in the magnetization of the ferrofluid by generation of the vapor bubbles during boiling process. The obtained results also showed that the simulated heat transport device powered based on magnetic-boiling induction is not only able to pump the ferrofluid through the tube, but also is able to transfer a considerable amount of heat generated in the electronic chip (heat source) as well. Furthermore, the flow rate of the induced flow inside the tube increases as the heat input of the heat source is increased. The heat source can be due to existence of a high heat flux electronic chip and the chip temperature (wall of the heated region) remains nearly unchanged during the flow boiling process in the heated region. The proposed magnetic- boiling driven heat transport device is usable in a closed circulating loop which can be extensively utilized in electronics cooling applications.
