The pharmaceutical industry requires the use of lubricants to prevent static electric buildup in the cohesive powders that are processed in manufacturing plants. In this report we examine the effects of common lubricant magnesium stearate on two flow properties, flow index and dynamic dilation, of lactose. We conducted two experiments using a gravitational displacement rheometer and a dynamic d...

The topologies are obtained for accretion flows around black holes as the parameters, accretion rate and specific angular momentum are varied. Paczyński-Wiita pseudoNewtonian potential is used to mimic the gravitational field of a Schwarzschild black hole. Both stellar mass(14M⊙) and supermassive(10 M⊙) black holes are considered. The effects of bremsstrahlung and synchrotron cooling processes ...

This paper proposes a hybrid technique for secured optimal power flow coupled with enhancing voltage stability with FACTS device installation. The hybrid approach of Improved Gravitational Search algorithm (IGSA) and Firefly algorithm (FA) performance is analyzed by optimally placing TCSC controller. The algorithm is implemented in MATLAB working platform and the power flow security and voltage...

Rock avalanches and landslides lead to gravitational flow into their runout areas, which poses increasing danger settlement areas infrastructure in the Alpine region as a result of climate change. In recent years, significant increase extreme events has been registered Alps due These changes threat have resulted need for construction sustainable protective structures. Many structures are rigid,...

The effect of preferential concentration of heavy particles in a homogeneous stably stratified turbulent flow is studied by means of direct numerical simulations. Particle distributions show different clustering patterns in horizontal and vertical directions, thereby representing the anisotropy of the flow. Preferential concentration in stably stratified turbulence can be quantified using 2D an...

Cohesive granular media flowing down an inclined plane are studied by discrete element simulations. Previous work on cohesionless granular media demonstrated that within the steady flow regime where gravitational energy is balanced by dissipation arising from intergrain forces, the velocity profile in the flow direction scales with depth in a manner consistent with the predictions of Bagnold. H...

The high-precision Juno gravitational measurements allow us to infer the structure of Jupiter's deep atmospheric zonal flow. Since this inference is nonunique, it important explore space possible solutions. In paper, we consider a model in which flow barotropic, or invariant along direction rotation axis, until truncated at depth by some dynamical process (e.g., Reynolds stress, Lorentz viscous...
