this article presents an experimental investigation on effects of morphology of nanoparticles on the viscosity nanofluids (nfs). water and ethylene glycol were used as base fluids. a two step method was used for preparation of nfs. sio2 nanoparticles, cnt and graphene nano sheets were dispersed in the base fluids separately with the volume fraction ranging from 0.05% to 1.5%. stability of the n...

The measurement of vortex flows with particle-image velocimetry (PIV) is particularly susceptible to error arising from the finite mass of the tracer particles, owing to the high velocities and accelerations typically experienced. A classical model of Stokes-flow particle transport is adopted, and an approximate solution for the case of particle transport within an axisymmetric, quasi-two-dimen...

The 1877 assumption/conjecture of Boussinesq is that turbulent fluctuations have a dissipative effect on the mean flow. The eddy viscosity hypothesis is that this dissipative effect can be modelled by a turbulent viscosity term. Many computational and experimental data sets have shown that the eddy viscosity hypothesis is not generally correct. The inverse cascade of energy to larger scales in ...

CFCs, HCFCs are stipulated to phase out, and other alternative refrigerants like R134a, are also constrained as a result from their high GWP values. CO2 as a natural working fluid now is used in reciprocating compressors due to its uniquely beneficial properties (ozone depletion potential, ODP=0; global warming potential, GWP =1). However, one remarkable characteristics of the CO2 reciprocating...

Batchelor and Handfield-Jones’s recommendation that cases of diagnostic uncertainty should be urgently referred to a dermatologist in secondary care does not stand up.Of the three cases presented, two needed to be excised by surgeons, and although not stated, almost certainly, so did the third—a tumour. The National Institute for Health and Clinical Excellence’s recommendation that all cases of...

Various authors have considered the Zero-rest-mass equation and the contour integral representation of its solutions. Ferber generalized these equations to supertwistor spaces with 2N odd components so that with N=O we get the standard ungraded twistors of Penrose. In this paper we use the Batchelor theorem toconstruct the natural super Twistor space with coarse topology with underlying sta...

Two-dimensional steady inviscid flow past an inclined flat plate with a forward-facing flap attached to the rear edge is considered for the case when a vortex sheet separates from the leading edge of the flat plate and reattaches at the leading edge of the flap, with uniform vorticity distributed between the vortex sheet and the body. Solutions are found for a particular geometry and a range of...
