WebWe derive exact formulae for the effective slip length for the pressure-driven longitudinal flow of a liquid (held in the Cassie--Baxter state) through a channel bounded by two superhydrophobic walls that are both etched with a periodic array of parallel grooves, where these arrays are symmetrically aligned. WebThe concept of The SH plane (generally anisotropic) exhibits uniform an effective tensorial slip has provided a great deal of in- tensorial slip [29], so that the boundary conditions are sides into various factors that determines flow in a flat channel, and allowed one to obtain very simple solutions ∂ (vτ )j of complex problems [9, 29].

WebOct 23, 2012 · This is an analytical study on electrohydrodynamic flows through a circular tube, of which the wall is micropatterned with a periodic array of longitudinal or transverse slip-stick stripes. One unit of the wall pattern comprises two stripes, one slipping and the other nonslipping, and each with a distinct ζ potential. WebDirect numerical simulations (DNSs) are used to investigate the drag-reducing performance of superhydrophobic surfaces (SHSs) in turbulent channel flow. SHSs combine surface roughness with hydrophobicity and can, in some cases, support a shear-free air–water interface. Slip velocities, wall shear stresses and Reynolds stresses are considered for a … WebJan 1, 2024 · The effects of the length of the cavity on the flow parameters such as effective slip length, and velocity slip are investigated and the results are compared with the simplified method of... ga hen\\u0027s-foot
