The reaction phenomena of CPOM (catalytic partial oxidation of methane) in a Swiss-roll reactor are studied numerically where a rhodium-based catalyst bed is embedded at the center of the reactor. CO2 is added into the feed gas and excess enthalpy recovery is performed to evaluate their...

A three-dimensional (3-D), transient, nonisothermal model of all-vanadium redox flow batteries (VRFBs) is developed by rigorously accounting for the electrochemical reactions of four types of vanadium ions (V2+, V3+, VO2+, and VO2+) and the resulting mass and heat transport processes. Particular...

This paper presents one kind of new car-following model (mean memory model, simplified as MMM) by introducing driver sensory memory (sensory buffer) term into the original optimal velocity (OV) function by Bando et al. (1995, 1998). The main improvement is that MMM can avoid the disadvantage of...

Vortex generators (VGs) are commonly-used effective flow separation control devices, and are proved to have potential to improve the aerodynamic performance of large wind turbines. In this paper, the flow physics of VGs and how their size affects the aerodynamic performance of a blunt...

Alpine basins are typically characterised by an amphitheatre shape with steep rocky walls on the upper, a deposition zone of glacial debris in the middle and a channel in the lower part. All different parts are in constant evolution, and different kinds of instability phenomena can be...

With the soaring energy demands, an urge to explore the alternate and renewable energy resources has become the focal point of various active research fronts. The scientific community is revisiting the inkling to tap the wind resources in more rigorous and novel ways. Recent idea of net-zero...

Alleviating the urban heat-island effect (UHI) is one of the important means to meet energy conservation and pollution reduction targets by demand side. Rational architectural layout and landscape design are significant measures to achieve building energy efficiency and sustainable building. In...

Having more than 2000 km tidal coastline, it's expected that Iran could exploit marine renewable energies. Furthermore, marginal countries around these seas are going to develop their energy resources and marine current energy can be a reliable choice. So, the results of a three dimensional...
