Damping and Frequency Shift in Microscale Modified Couple Stress Thermoelastic Plate Resonators
In this paper, the vibrations of thin plate in modified couple stress thermoelastic medium by using Kirchhoff- Love plate theory has been investigated. The governing equations of motion and heat conduction equation for Lord Shulman (L-S) [1] theory are written with the help of Kirchhoff- Love plate theory. The thermoelastic damping of micro-beam resonators is analyzed by using the normal mode a...
متن کاملThermoelastic Damping and Frequency Shift in Kirchhoff Plate Resonators Based on Modified Couple Stress Theory With Dual-Phase-Lag Model
The present investigation deals with study of thermoelastic damping and frequency shift of Kirchhoff plate resonators by using generalized thermoelasticity theory of dual-phase-lag model. The basic equations of motion and heat conduction equation are written with the help of Kirchhoff-Love plate theory and dual phase lag model. The analytical expressions for thermoelastic damping and frequency ...
متن کاملMicro-Scale Liquid-Liquid Separation in a Plate-Type Coalescer
The plate-type coalescer was constructed and tested for the continuous separation of immiscible liquids in micro-scale. Two plates formed the main structure of the coalescer. A flat and rectangular channel was situated between the plates. The material options for the plates were PTFE, stainless steel and glass which formed the contact surfaces for the fluids in the device. The liquid-liquid dis...
متن کاملThe Liquid Density of Complex Liquid Mixtures
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...
متن کاملUltrasonic Velocity, Density and Viscosity of Binary Liquid Mixtures of Acetone with Toluene, Chlorobenzene and Nitrobenzene
We report the measurements of the speed of sound in the binary liquid mixtures of acetone with toluene, chlorobenzene and nitrobenzene measured at 303 K. The studies on ultrasonic velocity, density and viscosity in binary liquid mixtures have been used to evaluate the different thermo acoustical parameters along with the excess properties. It was found that in all the cases, the experimental da...
