In this study, mass, stiffness and damping matrices of the Nosrat jacket; located in Persian Gulf; equipped with Semi Active Tuned Mass Damper (SATMD) system have been derived after modeling the structure in SACS software. Owing to huge number of the degrees of freedom in the model, computation of on-line control of SATMD was time consuming. For this purpose, the size of the model was reduced i...

166.6-MHz superconducting cavities have been chosen for the High Energy Photon Source (HEPS) as main accelerating structures to provide 900 kW of beam power and 5.4 MV voltage. A proof-of-principle cavity adopting quarter-wave beta = 1 geometry was previously developed. Excellent performance achieved in vertical tests at cryogenic temperatures. The later welded with a helium jacket, dressed cou...

the present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. the design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables. mor...

Microreactors have been widely used with advantageous of large specific surface area, excellent heat and mass transfer performance. In this paper, experimental numerical study were carried out to analyze the thermal hazard associated synthesis isopropyl propionate in a microreactor. study, effects reaction temperature, catalyst amount, channel diameter flow rate investigated. The optimal condit...

Based on the analysis of waste heat distribution characteristics a typical ship two-stroke low-speed main engine (model: MAN 8S65ME-C8.6HL, specified maximum continuous rating SMCR: 21,840 kW) under different loads, two types organic Rankine cycle (ORC) systems, namely basic system (BORC) and preheated system(PORC), were constructed to recover engine’s exhaust gas jacket cooling water heat. Usi...

The phosphorous acid salts are widely used in the industry because of effective treatment against various fungal diseases encountered plants. production process is exothermic and, with high temperatures around 94℃ achieved, significant risks were observed terms occupational health and safety. Therefore, aim to design a control system that will make this reliable for human health, economic ecolo...

This paper performed compressive tests on corroded reinforced concrete (RC) columns with externally confined ultra-high performance (UHPC) jacket. The studied parameters in this testing program was the corrosion ratio of specimens. influences parameter behavior by UHPC jacket reported and discussed. test results revealed that when rust rate less than 20%, axial cracking typical failure mode unr...
