The efficient use of renewable energy is receiving more and attention in the context “carbon neutrality” peaking”. For a long time, biomass has been used less efficiently as source, but with development fluidized gasification technology, it can play an increasing role industrial production. A bed gasifier strong nonstationary process due to its complex energy–mass exchange, analysis reaction pr...

 This work presents a model for calculating the effective ‎thermal conductivity of nanofluids. The proposed model ‎includes the effects of nanoparticles and thermal conductivity ‎base fluid.We will focus on experimental of the volume ‎concentration parameter and temperature on thermal ‎conductivity, nano-fluid combination and Multi-Walled ‎Carbon nanotubes-Oxide / Copper-paid deionized Water.

background: escherichia coli is one of the most important pathogens which could be transmitted by milk. the main aim of the present study was to assess risk factors related to the occurrence of e. coli in fluid milk marketed in chittagong, bangladesh. methods: totally, 169 milk samples were collected from different entry points in chittagong, bangladesh; and also, 17 samples were directly colle...

The primary cilium which is an organelle in nearly every cell in the vertebrate body extends out of the cell surface like an antenna and is known as cell sensor of mechanical and chemical stimuli. In previous numerical simulations, researchers modeled this organelle as a cantilevered beam attached to the cell surface. In the present study, however, we present a novel model that accommodates for...

This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...
