Industrial competitiveness of the ultrasonic-based technologies is reinforced by the relatively
low cost of power-generating equipment and ultrasonic transducers. However, further …

An increasing number of applications rely on the use of gas-fluidized beds of small particles
to enhance processes based on the mass/heat transfer between a gas and a solid. On the …

Abstract The Ca-Looping (CaL) technology, based on a dual gas-fluidized bed system of
CaO/CaCO 3 particles operated at high temperature, is a viable technological process for …

In this work, six different perspectives on characterizing the thermoacoustic field in an open-
ended Rijke tube are considered and discussed. These begin with a three-pronged …

In this work, we implement an asymptotic expansion technique that leverages a small
perturbation parameter that arises in the context of one-dimensional tubes with open-open …

In this article, an exact solution of the Navier–Stokes equations is presented for the motion of
an incompressible viscous fluid in a channel with arbitrary pressure distribution. A …

In this study, comprehensive numerical simulations were conducted to examine laminar
pulsatile developing flows through flat channels. The developing velocity fields and the …

The Ca-Looping (CaL) process, based on the multicyclic carbonation/calcination of CaO at
high temperatures, is a viable technology to achieve high CO2 capture efficiencies in both …

When a body immersed in a viscous fluid is subjected to a sound wave (or, equivalently, the
body oscillates in the fluid otherwise at rest) a rotational fluid stream develops across a …

In this work, an asymptotic expansion is further developed based on a naturally-occurring
perturbation parameter in the context of a one-dimensional tube with an open-open …
