Recent observations and theoretical work on gamma-ray bursts (GRBs) favor the central engine model of a Kerr black hole (BH) surrounded by a magnetized neutrino-dominated accretion flow (NDAF). The magnetic coupling between the BH and disk through a large-scale closed magnetic field exerts a torque on the disk, and transports the rotational energy from the BH to the disk. We investigate the pro...

The technique of laser micro-processing has recently found several important and widespread applications in the manufacturing of disk-drive components. Examples provided here include the cleaning of surface contaminants, the formation of “nano-bumps” on disk surfaces for controlled surface texturing or for making nanometer-height standards, and the micro-bending of magnetic head sliders for fli...

In this paper, micromixing is investigated in two Spinning Disk Reactors for liquids with increased viscosity. Glycerol and CMC were used as viscosity modifiers characterization was performed by means of the Villermaux–Dushman method. For first time, effects increasing pH bulk solution leading to disproportionation reaction iodine are successfully modeled. A kinetic model proposed account prese...

The purpose of this paper is to investigate the linear stability analysis for laminar-turbulent transition region high-Reynolds-number instabilities boundary layer flow on a rotating disk. This investigation considers axial along surface-normal direction, by studying analytical expressions steady solution, laminar, incompressible and inviscid fluid due disk in presence uniform injection suction...

We briefly overview the basic properties and generic behavior of circular equatorial particle orbits light rings around regular rotating compact objects with dark energy interiors, which are described by metrics Kerr–Schild class include black holes self-gravitating spinning solitons replacing naked singularities. These have an internal de Sitter vacuum disk can two types depending on condition...
