We investigate entropy generation in unsteady three-dimensional axisymmetric MHD nanofluid flow over a non-linearly stretching sheet. The flow is subject to thermal radiation and a chemical reaction. The conservation equations were solved using the spectral quasi-linearization method. The novelty of the work is in the study of entropy generation in three-dimensional axisymmetric MHD nanofluid a...

Our main focus in this paper is to investigate the effects of Soret and Dufour known as thermodiffusion diffusion-thermo on moving plate copper water nanofluid. The set partial differential equations are converted into ordinary using appropriate similarity variables before being solved numerically bvp4c code Matlab software. results heat mass transfer, temperature concentration profiles well pr...

Novel mixed antioxidants composed of antioxidant IPPD and lanthanum (La) complex were added as a filler to form natural rubber (NR) composites. By mechanical testing, Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) and thermogravimetric analysis (TGA), a string of data, including the mechanical properties, the variation of internal groups and the thermal and...

This paper reports on surface micromachined hinged structure assembly using thermo-kinetic forces in the molecular flow regime. Ultrasonic vibration energy is used to reduce the static friction making the thermo-kinetic force comparatively significant. The thermo-kinetic force, resulting from the more energetic gas molecules emanating from the heated substrate, increases with pressure and subst...

Optical forces in guided-wave nanostructures have recently been proposed as an effective means of mechanically actuating and tuning optical components. In this work, we study the properties of a photonic crystal optomechanical cavity consisting of a pair of patterned Si3N4 nanobeams. Internal stresses in the stoichiometric Si3N4 thin-film are used to produce inter-beam slot-gaps ranging from 56...
