An experimental investigation was carried out to determine the thermodynamics and fluid mechanics of the pipe flow of magnetic fluids. A water-based magnetic fluid was synthesized in the laboratory and its relative viscosity and magnetic properties were determined as a function of temperature. A "thermomagnetic pump" was built and tested in which temperature differences caused the magnetic fluid to circulate through a loop when subjected to a magnetic field. In a conceptual study, the pumping capabilities of such a flow circulation were considered for a thermal rejection system application. Pumping capabilities were observed to be directly related to the slope of the pyromagnetic curve. The sensitivity of the fluid was enhanced by the addition of zinc, manganese, and cobalt compounds. Fluid properties and flow parameters, including viscosity, magnetization, velocity, pressure, and temperature, were determined. A theoretical analysis was conducted for the prediction of values and analysis of the nature of the magnetic body forces induced in a magnetic fluid in the presence of heat and magnetic fields. A technique is introduced for the prediction of the maximum pressure difference that a "thermomagnetic pump" could produce. The advantages of a thermomagnetic pump are that it is noise free and reliable due to the absence of moving parts and control devices. At present, however, the flow rates generated by such a system are small and much research and development is needed for practical applications.

Download The Experimental Investigation of the Influence of a Longitudinal Magnetic Field on Convection Heat Transfer During Turbulent Flow of a Conducting Fluid in a Pipe Book in PDF, ePub and Kindle
The influence of a longitudinal magnetic field on convection heat transfer during turbulent flow of a conducting liquid in a pipe is studied, and an empirical formula for calculation of the heat transfer is subsequently offered. In general, at a constant Hartman number, the influence of the magnetic field decreases as the Reynolds and Peclet numbers increase. (Author).
