The deployment of nanocavities may efficiently enhance the light-matter interaction for photonic components on chip. Three nanoscale cavity designs are investigated, including the one-dimensional (1-D) photonic crystal (PhC) nanobeam cavity, inline waveguide-integrated plasmon cavity, and square plasmon resonator embedded in the 1-D PhC nanobeam cavity (i.e., Combo cavity). The cavity performan...

Early erbium and CO2 lasers failed to gain wide acceptance in the dental community because their optical drilling speeds were slower in comparison to the mechanical bur. This has changed in the past few years; much faster ablation speeds are now possible and dental lasers with variable square pulse technology even exceed the drilling speeds of conventional burs. In this paper we report on a cli...

In this study, mixed convection heat transfer and local and global entropy generation in aventilated square cavity have been investigated numerically. The natural convection effect isachieved by a constant heat flux imposed at the bottom wall and cooled by injecting a coldfollow. In order to investigate the effect of port location, four different placementconfigurations of the inlet and outlet ...

OBJECTIVE In this paper, cavity experiences of children with different levels of eruption and cavity activities that are enrolled at an elementary school with semi-rural characteristics in Kırıkkale Provincial center were monitored for 2 years after a variety of protective applications. MATERIALS AND METHODS Three hundred and twenty-two children at the age of 7-11 were included in this study....

In the present study, natural convective heat transfer in a partitioned square cavity utilizing nanofluids is studied. The vertical left and right walls are considered as the hot and cold walls, respectively and the partitions assumed to be adiabatic. The nanofluid used in this study is Al2O3 with the volume fraction of 20%. It is assumed that nanofluid is a single phase f...

Two-dimensional numerical study of flow and temperature fields for laminar natural convection and radiation in the inclined cavity is performed in the present work. The walls of the square cavity are assumed kept at constant temperatures. An absorbing, emitting, and scattering gray medium is enclosed by the opaque and diffusely emitting walls. The set of governing equations, including conservat...

The Lagrangian transport in the laminar incompressible flow a two-dimensional square cavity driven by harmonic tangential oscillation of lid is investigated numerically for wide range Reynolds and Strouhal numbers. topology fluid trajectories analyzed stroboscopic projections revealing co-existence chaotic regular Kolmogorov–Arnold–Moser (KAM) tori. pathline structure strongly depends on number...
