The study applies the Corcione model to hybrid nanofluids, which considers viscosity, conductivity, and the size of the nanoparticle, temperature, and Reynolds number. The cavity is connected to a rectangular channel, with the cavity's length being half the total length of the enclosure, and the aspect ratio (cavity height divided by height of the channel) is tested from 1 to 3. The study uses the Navier–Stokes equation and energy equation in two dimensions, along with finite element-based software, COMSOL 5.6, to simulate the combination of fluid flow and heat transmission. The results show a circular distribution of temperature in the cavity, and the average temperature drops as the volume fraction of copper upsurges. However, both the Reynolds number and volume fraction of copper improve the average Nusselt number, which s...

We study the optical properties of the electromagnetic simulation of silver nanoparticle in far field and near fields. Silver nanoparticles have unique optical and electronic properties which make them suitable for biosensing applications. The interaction of light with silver nanoparticle produces a collective oscillation of conduction band electron known as localized surface plasmon resonance. Plasmon resonance occurs when the frequency (wavelength) of the source is equal to the target frequency. Around this peak wavelength, we can detect the presence of desired target. To simulate the extinction cross section of silver nanoparticle in the Plasmonic resonance peaks in far and near fields, Finite Difference Time Domain (FDTD) method is applied. In our investigations the optical properties of plasmon resonance peak position occur in the visible and near infrared light (400 nm to 800 n...
