This paper presents a detailed numerical simulation of the fluid flow characteristics of a synthetic jet. The fluid motion is caused by an oscillating piston within a circular channel which is connected to a larger cavity. The oscillating piston utilized a sawtooth forcing profile, and the solution encompassed the channel geometry, the cavity, and the fluid domain external to the cavity. Moment...

Herein, a novel cavity design of racetrack integrated circular established on metal-insulator-metal (MIM) waveguide is suggested for refractive index sensing application. Over the past few years, we have witnessed several unique designs to improve performance plasmonic sensors created MIM waveguide. The optimized can provide best performance. In this work, numerically analyzed device by utilizi...

The cavitation characteristics were experimentally investigated about long circular-cylindrical orifices of various throat lengths including the orifice with a trip wire. Especially, the shedding process of separated vortex cavity was examined in detail with the observation using high-speed photography. The cavitation impact was measured with an accelerometer. As a result, it is found that the ...

An elastocapillary model for drying-induced collapse is proposed. We consider a circular elastic membrane with a hole at the centre that is deformed by the capillary pressure of simply and doubly connected menisci. The membrane overlays a cylindrical cavity with rigid walls, trapping a prescribed volume of water. This geometry may be suitable for studying structural failures and stiction in mic...

A magnetohydrodynamic (MHD) stirrer that exhibits chaotic advection is investigated experimentally and theoretically. The stirrer consists of a circular cavity with an electrode (C) deposited around its periphery. Two additional electrodes (A) and (B) are deposited eccentrically inside the cavity on the bottom. The cavity is positioned in a uniform magnetic field that is parallel to the cylinde...

This paper studies the effect of dielectric cover layer thickness on circular microstrip patch antenna parameters such as gain, bandwidth, beam-width, radiation patterns, return loss and VSWR. The proposed is designed with 2.4GHz frequency in S-Band region. operating useful ISM band applications. Circular cavity model analysis simulated using HFSS simulation software (Electromagnetic simulator)...

In geometric inverse problems, it is assumed that some parts of domain boundaries are not accessible and geometric shape and dimensions of these parts cannot be measured directly. The aim of inverse geometry problems is to approximate the unknown boundary shape by conducting some experimental measurements on accessible surfaces. In the present paper, the artificial neural network is used to sol...
