The purpose of this work is to study the effect of oscillatory MHD blood flow in stenosed artery. The analytical and numerical results are obtained for oscillatory MHD blood flow, which is assumed to be a Newtonian fluid. It was also assumed that the surface roughness is of cosine shaped and the maximum height of roughness is negligible, compared with the radius of un-constricted tube. The flui...

this pump could be used to irrigate the regions where ground water level is close to land surface and thire is enough wind energy in the region. since advanced pumps are costly, this pump is designed only to send up water one meter high with the flow of one.inexperimental fluid mechanics laboratory of orrsay france amodel of this pump was conducted. results show that the pump could be manufactu...

the primary cilium which is an organelle in nearly every cell in the vertebrate body extends out of the cell surface like an antenna and is known as cell sensor of mechanical and chemical stimuli. in previous numerical simulations, researchers modeled this organelle as a cantilevered beam attached to the cell surface. in the present study, however, we present a novel model that accommodates for...

[1] A detailed understanding of the coupling between fluid and solid mechanics is important for understanding many processes in Earth sciences. Numerical models are a popular means for exploring these processes, but most models do not adequately handle all aspects of this coupling. This paper presents the application of a micromechanically based fluid-solid coupling scheme, lattice-Boltzmann di...
