چکیده
Effects of magnetic field strength and direction were studied on the fluidization of titanium oxide nanoparticles (anatase phase) with ferromagnetic iron (III) oxide nanoparticles. The main hydrodynamic structures were defined and studied using wavelet transform. Energy analysis was used to study the effect of the field direction and strength on fluidization. The results suggested that mesostructures (agglomerates) have the most effect on the nanoparticle fluidization characteristics. Higher energy at high field strength for upward direction, suggests more intense interaction between agglomerates in the bed for nanoparticles that result in more stochastic pattern and lower ABF regime characteristics. Downward direction at low magnetic field strength shows improving the fluidization quality by the effect of the vibration of the solenoid. It was observed that at low field strength, vibration has a major effect on fluidization than the magnetic force. At high magnetic field strength, as the magnetic force becomes stronger, the downward field decreases the energy of finer structure (agglomerates) which leads to less movement and resistance against fluidization.
