A new technique for the strengthening of existing R/C shear walls based on the application of very thin high performance jackets is presented in this paper. The strengthening jacket is made of high performance concrete and high strength steel mesh. The experimental study on a 1:3 scale R/C wall, proportioned to resist the vertical loads only, and reinforced by means of a 15 mm thick high perfor...

Reliability of liquid rocket engines is strictly connected with the successful operation cooling jackets, able to sustain impressive operative conditions in terms huge thermal and mechanical loads, generated thrust chambers. Cryogenic fuels, like methane or hydrogen, are often used as coolants they may behave transcritical fluids flowing jackets: after injection a state, phase pseudo-change occ...

While in the first paper of this series of two, optimal jacket fluid temperature control profiles have been derived for a family of dispersive tubular chemical reactors, the performance of these optimal profiles is further assessed in this second part. First, the performance of the optimal bang-bang control is compared with that of a more easily implementable constant jacket fluid temperature a...

Regarding the previous earthquake damages in offshore structures, as vital structures in the oil and gas industries, it is important that their seismic design will be performed with very high reliability. Accepting the Nonlinear Time History Analyses (NLTHA) as the most reliable seismic analysis method, in this paper an offshore platform of jacket type with the height of 304 feet and with a dec...

The problem of automating the thermal calculation a reactor for synthesis sulfur-containing sorbent wastewater treatment from heavy metal compounds using chlorlignin is considered. A formal description algorithm and block diagram are given; interface program written in C#, displaying results heating working mixture, determining amount heat suspension, transfer coefficient medium to wall, mass f...
