Modelling the wall collision of regular non-spherical particles and experimental validation
(The Amarican Society of Mechanical Engineers (ASME),, 2014)
The importance of numerical calculations (CFD) for supporting the optimization and lay-out of industrial processes involving multiphase flows is continuously increasing. Numerous processes in powder technology involve ...
Modelling and Simulation of Drag Forces of Non-spherical Particles Moving Towards a Surface in Polymer Melt Flows
(Elsevier Science, 2017-07)
This work deals with the drag forces acting on non-spherical particles translating normal to a surface in a polymer melt in which the particle–surface distance is small compared with particle dimension in the flow direction. ...
Surface temperature distribution on a spherical ice particle growing by accretion in wet growth regime
(John Wiley & Sons Ltd, 2019-10)
Experimental evidence has demonstrated that temperature on the surface of an ice particle growing by accretion is not uniform. This non-uniformity is relevant because the ice particle surface temperature is an important ...
Aerodynamic coefficients of irregular non-spherical particles at intermediate Reynolds numbers
(Elsevier, 2022-03)
In industrial processes such as those related with paper industry, coal or biomass combustion, particles can take
irregular non-spherical shapes. However, in related numerical computations the assumption of spherical ...
Pressure center determination for regularly shaped non-spherical particles at intermediate Reynolds number range
(Elsevier, 2021)
The present contribution aims to determine the dependence of the location of the non-dimensional center of pressure ( with orientation () for non-spherical particles of regular shape. Prolate and oblate ellipsoids as well ...
Non-leachable highly luminescent ordered mesoporous SiO2 spherical particles
(Iop Publishing Ltd, 2010-04-16)
Ordered mesoporous highly luminescent SiO2 particles have been synthesized by spray pyrolysis from solutions containing tetraethylorthosilicate (TEOS) and either cetyltrimethylammonium bromide (CTAB) or the block copolymer ...
