2014 In this paper we treat for the first time a phenomenon in micellized soap solutions which arises uniquely from their being colloidal suspensions whose « particles » do not maintain their integrity. In particular we focus on the growth of anisotropic aggregates which is attendant upon their long-range orientational ordering. We consider a simple analytical form for the free energy per molec...

A probe is an important part of high-precision thread-measuring machines. Probe design affects the ability machine to achieve precision. The development three-dimensional (3D) machines has mandated strict requirements for matching measuring heads. contact scanning offers advantages a relatively high measurement accuracy and stable performance. In this study, structure was designed. First, micro...

In this study, the mixed convection heat transfer in a mechanical ball bearing filled with nano-lubricants were investigated theoretically. our case, including eight balls revolving counter clockwise while inner shaft rotates direction and outer walls of kept at constant hot cold temperatures, respectively. Two kinds SiO2-water Alumina- Polyalphaolefin (PAO) different shapes nanoparticles consi...

We propose a finite element method for simulating one-dimensional solid models with thickness and length that move experience large deformations while immersed in generalized Newtonian fluids. The is oriented towards applications involving microscopic devices or organisms the soft-bio-matter realm. By considering strain energy of may explicitly depend on time, we incorporate mechanism active re...
