Application of a Non-intrusive Optical Non-spherical Particle Sizing Sensor at Turboshaft Engine Inlet
… dangerous. In order to combat these issues, a particle sensor with the ability to monitor in-stream particulate size, shape, and mass flow rate is necessary. Our team with the Advanced Propulsion and Power Laboratory developed a non-intrusive optical sensor that is able to characterize …

Modeling and simulation of micro/nano-rod distribution in micro channel flows
<p>"The behavior of a typical nanorod particle in microscale flows was theoretically investigated, considering the effect of the wall on the rotational and translation motions of the non-spherical particle. Initially, a systematic method using Brownian dynamics simulation of the rotational motion …

CFD – DEM Modeling and Parallel Implementation of Three Dimensional Non- Spherical Particulate Systems
… combustion, blood cellular systems and granular particles in fluidized beds, have often been computationally represented using spherical surfaces, even though the majority of particles in archetypal fluid-solid systems are non-spherical. While spherical particles are more cost-effective to …

Learning-Based Control for Optically Trapped Non-Spherical Particles
… in most situations, becomes significant toparticle dynamics when the particle size is on the micron-scale or smaller. An optical tweezers system harnesses the momentum of light to manipulate these small particles by trapping them near the focal point of a sharply focused laser beam. Since …

Advancing Cold Spray for Additive Manufacturing: A Study on Particle Morphology, Gas Nature, and Particle Preheating
… review, and conclusion. The effect of a non-spherical particle morphology was the first objective investigated. Titanium has been shown repeatedly to require pure helium at very high temperatures and pressures to get dense coatings, however, the unique coral-like morphology resulting from …

Study of Fluid Forces and Heat Transfer on Non-spherical Particles in Assembly Using Particle Resolved Simulation
… systems. Most of the studies have focused on spherical particle shapes, however, in most natural and industrial processes, the particle shape is seldom spherical. In fact, particle shape is one of the important parameters that can have a significant impact on momentum, heat and mass transfer, …

Microscale dynamics in suspensions of non-spherical particles
… the microscale dynamics in suspensions of spherical and non-spherical particles. Two new algorithms were developed to enable studies with accurate hydrodynamics. The first algorithm was a high accuracy Stokesian Dynamics technique (SD) extended to a generic non-spherical particle shape. The …
