an s-curve to describe the gradual transition between exhaust pressure and intake or inlet pressure. The start of compression, which marks the end of the intake process, does not necessarily occur at the same time as the close of the intake valve (IVC). The intake valve closes after bottom center (BC) while the volume in the cylinder is decreasing. The engine speed determines the point at which...
In this paper, the plastic deformation of clamped rectangular steel plates is investigated both experimentally and numerically using gases mixture detonation approach. In this series of experimental tests, the steel plates with various thicknesses were deformed under shock wave effect which had been caused by high velocity rate explosion. Also, the pressure of gases mixture detonation was measu...
biofiltration of triethylamine (tea) vapor used as a catalyst in casting operations was evaluated in this study. the unit consisted of a 6-l three-stage biofilter containing a mixture of compost and wood chips (40:60 v/v) as the filter medium. seed microbial population from municipal activated sludge was acclimated for a period of three weeks prior to the actual experimental runs. in the startu...
In this paper, the resonance optical absorption method, is used to measure the Cu atoms number density in different power levels of power supply. Atoms are sputtered from a Cu target during plasma magnetron sputtering deposition. For the light source, a commercial Cu hollow cathode lamp is used. For measurement of gas temperature, a small percentage of N2 is added to the gas mixture and the gas...
In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...
in this paper, a recurrent fuzzy-neural network (rfnn) controller with neural network identifier in direct control model is designed to control the speed and exhaust temperature of the gas turbine in a combined cycle power plant. since the turbine operation in combined cycle unit is considered, speed and exhaust temperature of the gas turbine should be simultaneously controlled by fuel command ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
This work focuses on the development and improvement of numerical tools for the simulation of catalytic monolith reactors. These simulations cover detailed descriptions of reaction mechanisms, transport in gas-phase and washcoats, fluid flow in single channels, and the entire reactor. In DETCHEM, the concept of building a transient model of the monolith reactor by the calculation of steady-stat...
The paper presents the results of experimental and model tests transport dispersed fluid droplets forming a cloud aerosol in stream air ventilating selected section underground excavation. excavation for testing is part ventilation network Experimental Mine Barbara Central Mining Institute. For given environmental conditions, such as temperature, pressure, relative humidity, velocity air, distr...
