Elastic energy propagation in a strongly scattering 1D laboratory model

Laboratory ultrasonics provides an ideal opportunity for studying wave propagation in random media. Models are relatively easy to construct and both the phase and amplitude of the wave field can be measured, so we can separate the coherent from the incoherent intensity. Here we show detailed measurements of wave propagation in a 1D strongly scattering medium that fit the theory of radiative tra...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Wave Propagation at the Boundary Surface of Elastic Layer Overlaying a Thermoelastic Without Energy Dissipation Half-space

The present investigation is to study the surface wave propagation at imperfect boundary between an isotropic thermoelastic without energy dissipation half-space and an isotropic elastic layer of finite thickness. The penetration depth of longitudinal, transverse, and thermal waves has been obtained. The secular equation for surface waves in compact form is derived after developing the mathemat...

Stress Wave Propagation in Elastic-elastic and Elastic-viscoelastic Bilaminates

In the present study normal plate-impact experiments are conducted to investigate the propagation of acceleration waves in 2-D layered material systems. The objective of these experiments is to understand the role of material architecture and material inelasticity in controlling precursor decay and late-time dispersion of acceleration waves in elastic-elastic and elasticviscoelastic laminates. ...
