Effects of micro-grooves and fluid viscoelasticity on friction drag reduction in a turbulent boundary layer

Engineering Applications of Computational Fluid Mechanics
To meet the underwater drag reduction needs in engineering applications, one can draw on the drag reduction strategies of marine animals such as sharks, utilizing their surface groove structures and the secretion of viscoelastic drag-reducing mucus to ...

Flow of viscoelastic fluid in curved tube (Visualization of flow in curved tube and analytical optimization by finite element method)

Nihon Kikai Gakkai ronbunshu, 2015
In the present study we report the flow characteristics of a steady flow of viscoelastic fluid in a curved pipe of 90 degree bend. The liquid mode consideration is a model-fluid, which is newly made to investigate the viscoelastic fluid.

Combined Stereoscopic Particle Image Velocimetry and Line Integral Convolution Methods: Application to a Sphere Sedimenting Near a Wall in a Non-Newtonian Fluid. [PDF]

, 2005
The flow fields for a sphere sedimenting through a Newtonian and two non-Newtonian liquids near a wall in a square tank are investigated using 3-D stereoscopic particle image velocimetry (PIV) and line integral convolution (LIC) methods.

Effect of magnetic field on thermal instability of a rotating Rivlin-Ericksen viscoelastic fluid

International Journal of Mathematics and Mathematical Sciences, 2006
The thermal instability of a rotating Rivlin-Ericksen viscoelastic fluid in the presence of uniform vertical magnetic field is considered. For the case of stationary convection, Rivlin-Ericksen viscoelastic fluid behaves like a Newtonian fluid.

Significant consequences of heat generation/absorption and homogeneous-heterogeneous reactions in second grade fluid due to rotating disk

Results in Physics, 2018
Flow of second grade fluid by a rotating disk with heat and mass transfer is discussed. Additional effects of heat generation/absorption are also analyzed. Flow is also subjected to homogeneous-heterogeneous reactions.
