We experimentally investigate the effect of shape on finite-size particles long term trajectories and observe that with an anisotropic can be attracted to coherent regions flow a higher rate than spherical particles. present simple model combines effects orientation-dependent drag forces, show aggregation final particle concentration depend both particle's Stokes number aspect ratio.

primary assumption in most problems of elasticity theory in petroleum geophysics is that the elastic media is isotropic. laboratory experiments confirmed that most rocks are anisotropic. if in one medium, properties vary with directions, it is named as anisotropic. knowledge about anisotropy reduces risk and cost of hydrocarbon production. in the present study, anisotropy of a carbonate reservo...
