Article history: Received 29 October 2015 Received in revised form 18 December 2015 Accepted 19 December 2015 Available online 29 December 2015 Particle shape plays an important role in determining the engineering behaviour of granular materials. In this regard, characterisation and quantification of particle shape are essential for understanding the behaviour of granular materials. X-ray micro...

Particle shape of wastewater effluents were investigated by implementing a dynamic particle image analyzer which provided data on the particle count, size, shape and circularity concurrently with images. The goals of this study were to characterize removal efficiency based on size and shape parameters for an in-line filtration process and to study correlation between size and shape parameters. ...

objective(s): it has been suggested that the efficiency of dry poder inhaler (dpi) is generally low. therefore, the aim of the present research work was to use the solvent treatment of the carrier in dpiformulations to see the possibility of inducing desirable characteristics.   materials and methods: lactose sieve fractions of 63-90 μm were submerged in ethanol or 80% v/v ethanol, methanol or ...

the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

Steady, continuum, laminar plasma flow over spheroidal particles has been numerically investigated in this paper using a finite volume method. To body-fit the non-spherical particle surface, an adaptive orthogonal grid is generated. The flow field and the temperature distribution are calculated for oblate and prolate particle shapes. A number of particle surface temperatures and far field tempe...
