Study on water infiltration into oil-base magnetic fluid

The influence of magnetic field,concentration of mannetic particle,and stirring time on the infiltration of deionized and saline water into oil base magnetic fluids were investigated by TGA method.The results showed that the water infiltration into oil-base magnetic fluid increases and decreases with increasing magnetic field and volume fraction of magnetic particles,respectively Compared with the deionized water,the salt water has an unremarkable tends to inhibit water infiltration into oil-base magnetic fluid.But as the scouring time extends,the infiltration rate gradually reduces.
