superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °c without any subsequent calcination. the composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using x-ray diffraction (xrd), field emission scanning electron microscope (fesem), transmission electron microscope (tem), fou...

A hybrid axisymmetric conservative phase-field lattice Boltzmann method is applied to investigate the influence of Marangoni number ( Ma ), density ratio ρ r and radius R ) on thermocapillary migration a deformable hollow droplet with difference in variable fluid properties, where (radius) part droplet. The isotherms show that heat transfer around changed from conduction convection increase . H...

This study compares the free-surface lattice Boltzmann method (FSLBM) with conservative Allen–Cahn phase-field (PFLBM) in their ability to model two-phase flows which behavior of system is dominated by heavy phase. Both models are introduced and individual properties, strengths weaknesses thoroughly discussed. Six numerical benchmark cases were simulated both models, including (i) a standing gr...

potential fields are due to complex distribution of sources related to susceptibility and mass density variations for magnetic and gravity field respectively. in researching the lateral heterogeneous of different geological bodies, in particular their edge location potential field has some advantages. we mainly refer to linear features such as fault, folding axis, dyke, trend and border of the ...
