The hydrodynamic behaviors of sperms in confined spaces (e. g. Poiseuille flow and quiescent flow between two parallel walls) are studied with a two-dimensional self-propelled sperm model based on the immersed boundary-lattice Boltzmann method (IB-LBM). https://www.bekindtopets.com/mega-sale-Equi-Jec-7-amazing-offer/
