Experimental Study of Pool Boiling Heat Transfer of Water-Based Magnetic Fluid on a Horizontal Heater

The effect of mass concentration of magnetic particles and an applied magnetic field on pool boiling heat transfer of water-based magnetic fluid on a horizontal heater was investigated. The experimental results show that high-concentration magnetic fluid deteriorates boiling heat transfer, while middle-and low-concentration magnetic fluid enhances the boiling heat transfer. There was an optimum concentration in which the enhancement of boiling heat transfer was the best. Conclusions were the same with an applied magnetic field that enhances the boiling heat transfer of magnetic fluid further. (C) 2005 Wiley Periodicals, Inc.
