TL;DR: In this article, the authors investigated the non-linear dynamics and stability of simply supported, circular cylindrical shells containing inviscid incompressible fluid flow, and showed that the system loses stability by divergence.

TL;DR: In this article, a review of the literature on the area of heat transfer improvement employing a combination of nanofluid and inserts is performed, and the progress made and current challenges for each combined system are discussed, and some conclusions and suggestions are made for future research.
Abstract: Improving heat transfer is a critical subject for energy conservation systems which directly affects economic efficiency of these systems. There are active and passive methods which can be employed to enhance the rate of heat transfer without reducing the general efficiency of the energy conservation systems. Among these methods, passive techniques are more cost-effective and reliable in comparison with active ones as they have no moving parts. To achieve further improvements in heat transfer performances, some researchers combined passive techniques. This article performs a review of the literature on the area of heat transfer improvement employing a combination of nanofluid and inserts. Inserts are baffles, twisted tape, vortex generators, and wire coil inserts. The progress made and the current challenges for each combined system are discussed, and some conclusions and suggestions are made for future research.

TL;DR: In this paper, a plasma reactor apparatus is described in which plates having channels are used to redistribute gas uniformly over the surface of a wafer being processed in the reactor, and slots adjacent the plates provide a final baffle to prevent jetstreams in the gas from impinging directly on the wafer.
Abstract: A plasma reactor apparatus is disclosed in which plates having channels are used to redistribute gas uniformly over the surface of a wafer being processed in the reactor. Slot means adjacent the plates provide a final baffle to prevent jetstreams in the gas from impinging directly on the wafer.

TL;DR: In this article, the heat transfer coefficients of shell and helically coiled tube heat exchangers were investigated experimentally, and the calculated heat transfer coefficient of tube-side were also compared to the existing correlations for other boundary conditions and a reasonable agreement was observed.
