Deterministic lateral displacement (DLD) is a popular technique for separating micro-scale and nano-scale particles continuously. In this paper. an efficient three-dimensional fictitious domain method is developed for the direct numerical simulation of the motion of a non-colloidal spherical particle in the DLD device (i. e. https://www.remtavares.com/limited-find-Interstella-Sequin-Long-Sleeve-Mini-Dress-Black-huge-savings/
