A numerical solution of the steady boundary layer equations under similarity assumptions is obtained for the three-dimensional flow of a micropolar fluid over a continuous stretching surface. The case when microrotation vector is zero on the solid surface is considered. Using properly similarity variables, the three-dimensional Navier – Stokes equations are reduced to a set of four coupled non-...

The self similar steady boundary layer flow induced by a permeable continuous surface stretching with velocity Uw (X) = A. x −1/2 in a quiescent incompressible fluid in the presence of a transverse magnetic field of uniform strength Bo, with suction velocity Vw(x) = − ( υA 4 ) 1/2 . xfw is considered. Numerical solution of the resulting similarity momentum equation using Runge-Kutta-Fehlberg Fo...

Ultrafast vibrational dynamics of cyclic hydrogen bonded dimers and the underlying microscopic interactions are studied in temporally and spectrally resolved pump-probe experiments with 100 fs time resolution. Femtosecond excitation of the O-H and/or O-D stretching mode gives rise to pronounced changes of the O-H/O-D stretching absorption displaying both rate-like kinetic and oscillatory compon...

The effects of ion charge, polarity and size on the surface morphology of size-selected aqueous nanodrops containing a single ion and up to 550 water molecules are investigated with infrared photodissociation (IRPD) spectroscopy and theory. IRPD spectra of M(H2O)n where M 1⁄4 La, Ca, Na, Li, I , SO4 and supporting molecular dynamics simulations indicate that strong interactions between multiply...

This paper deals with the double-diffusive boundary layer flow of non-Newtonian nano-fluid over a stretching sheet. In this model, where binary nano-fluid is used, the Brownian motion and thermophoresis are classified as the main mechanisms which are responsible for the enhancement ofthe convection features of the nanofluid. By means of the successive approximation method the governing equation...

In this paper we present simulations of a surface-adsorbed polymer subject to an elongation force. The polymer is modelled by a self-avoiding walk on a regular lattice. It is confined to a half-space by an adsorbing surface with attractions for every vertex of the walk visiting the surface, and the last vertex is pulled perpendicular to the surface by a force. Using the recently proposed flatPE...
