A micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. Governing equations were solved base on the finite volume method with FLUENT software. In upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. Two sections were separated with solid part which played as heat exchanger and trans...

Algal biofuels are intriguingly a renewable energy source that could partially substitute fossil fuels, but further research is required to optimise the growth parameters and establish competitive large-scale cultivation systems. directly dependent on momentum, heat, mass transfer within photobioreactor environmental conditions. Therefore, in this computational study, heat between thin-layer ca...

A microbial fuel cell (MFC) is a device that converts organic matter to electricity using microorganisms as the biocatalyst. Most MFCs contain two electrodes separated into one or two chambers that are operated as a completely mixed reactor. In this study, a flat plate MFC (FPMFC) was designed to operate as a plug flow reactor (no mixing) using a combined electrode/proton exchange membrane (PEM...

multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

Helium flow in the rod bundle channel with an open lattice structure is important phenomenon for advanced gas-cooled nuclear core design. In this study, thermal analysis helium various designs conducted based on CFD methods to determine a dimension-optimized channel. An experimental study then follows order pick up appropriate gas model further numerical simulation. Finally, channels consisting...

The efficiency of a thermochemical energy storage system can be improved by optimizing the structure reactor. We proposed two modified structures for indirect heat transfer reactors Ca(OH)2/CaO to improve their performance. Our results showed that improving convective offered varying effects on performance in different reaction processes. For half-plate pin fin sinks (HPPFHS) reactor and plate ...
