Highly-effective sustainable hydrogen production from ethanol and water was achieved in a tubular dense mixed-conducting oxygen permeable membrane reactor, in which water splitting took place at the tube side of the membrane and oxidative steam reforming of ethanol occurred at the shell side simultaneously.

The paper presents a survey of the experimental and numerical studies shell-and-tube systems in which phase change material (PCM) is used. Due to multitude design solutions for systems, emphasis placed on double-tube (DT), triplex-tube (TT), multi-tube (MT) units. Additionally, only single-pass are considered. Particular attention paid method heat transfer intensification. analysis research res...

Viscous ow in elastic (collapsible) tubes is a large-displacement uid-structure interaction problem frequently encountered in biomechanics. This paper presents a robust and rapidly converging procedure for the solution of the steady three-dimensional Stokes equations, coupled to the geometrically non-linear shell equations which describe the large deformations of the tube wall. The uid and soli...

An Adaptative Neuro-Fuzzy Inference System (ANFIS) is developed to predict the acoustic form function (FF) for an infinite length cylindrical shell excited perpendicularly to its axis. The Wigner-Ville distribution (WVD) is used like a comparison tool between the calculated FF by the analytical method and that predicted by the neuro-fuzzy technique for a copper tube. During the application of t...
