The numerical modelling and process simulation for the fault diagnosis of rotary kiln incinerator were accomplished. In the numerical modelling, two models applied to the modelling within the kiln are the combustion chamber model including the mass and energy balance equations for two combustion chambers and 3D thermal model. The combustion chamber model predicts temperature within the kiln, fl...

In this paper are presented the results obtained by modelling and simulation of the combustion in a turbojet engine. The study of the mathematical model represented by the equations which described the combustion process was made by using the software FLUENT 6.1. The paper is focused on the establishment of the link between the control laws of the turbojet engine (whose main parameter is the fu...

Due to the difficulty directly study ammonia, present work investigated engine performance of lean iso-octane/air mixture approximate ammonia combustion behaviour. The was conducted using a single cylinder modified diesel that features spark plug and glow in sub-chamber. investigations varied speeds (1000 1500 RPM), voltages (6 10 volts), excess air ratios (1.4 1.8), ignition timings (-2 -5 °BT...

This work focuses on the nonlinear control of instabilities in the combustion of a diluted dimethyl ether (DME) / air mixture under low temperature conditions. A nonlinear model predictive control (NMPC) is utilized to stabilize the combustion in simulation with the aim to specify minimum actuation dynamic requirements and develop control strategies for an existing experimental chemical reactor.

Graphene is a monolayer carbon atoms discovered in the recent past which has inspired researchers in a wide range of applications. It has a surface area as high as 2630 m2/g and thermal conductivity value of 3000 W/mK-1 at room temperature. It is chemically the most reactive form of carbon with one carbon atom exposed to reaction from each side. Stable dispersion of graphene was achieved using ...

Current legislation in European countries, as well as in other parts of the world, is putting stricter limits on pollutant emissions from road vehicles. This issue, in conjunction with the increase awareness of consumer for the environmental problems, will require the development of new clean propulsion systems in disruption with the current mobility solutions based on internal combustion engin...

Introduction: The neural substrates of temporal processing are not still fully known. The majority of interval timing studies have dealt with this subject in the context of “Explicit timing” (computing the time intervals explicitly). The hypothesis “Implicit timing” (implicitly using temporal processing to improve function) has also proposed. This lesion study addressed explicit and implicit ti...

Yoshihiro Sukegawa Kazuhiro Oryoji Eiji Ishii, Dr. Eng. OVERVIEW: Improving the fuel economy and emissions of vehicle engines requires a detailed understanding of the various physical processes taking place inside the engine so as to identify optimal combustion control techniques and engine component designs. Based on numerical techniques established by its power plant business for the analysis...
