Nanofluids play an important role in many different industries for improvement of heat transfer. The modeling and simulation such fluids is developing continuously. Two models studying nanofluids are mixture (or single-phase) two-phase Buongiorno) forms, which have been examined various ways. Non-Newtonian behavior (shear-thinning viscoplasticity) has observed experimental tests simulated sever...

It is becoming widely recognized that, contrary to earlier expectations, the usual one-band Hubbard model does not give an explanation for itinerant ferromagnetism. After reviewing the status of magnetic ordering in the one-band model, we discuss the possibility of ferromagnetism in some recently introduced two-band Hubbard models, and in generalized Ander-son lattices. It is argued that these ...

Effects of binary mixtures of ionic/nonionic (sodium dodecyl sulfate/2-heptanol or 1-decanol) and nonionic/nonionic surfactants (2-heptnol/1-decanol) on drop/interface coalescence of water drops in a continuous n-heptane phase were examined. The drop size reduced appreciably and the multi-step coalescence was suppressed finally as the concentration of each of the constituting components</em...
