Due to the high operating temperature of solid oxide fuel cells (SOFC), system efficiency depends on efficient thermal integration and effective construction configuration. In this study, nine configurations design were investigated evaluate possible improvement with energy separation devices. The models developed under Matlab/Simulink® platform Thermolib® module. reference layout simulation in...

The use of alternative fuels to traditional kerosene-based ones in turbo-jet engines is currently being widely explored and researched. However, the application area small turbojet with thrust ratings up 2 kilo-newtons, which are used as auxiliary power units or propel aircraft drones, not well This paper explores ethanol a sustainable fuel its effects on operation engine under laboratory condi...

Abstract We are concerned with the simulation and optimization of large-scale gas pipeline systems in an error-controlled environment. The flow dynamics is locally approximated by sufficiently accurate physical models taken from a hierarchy decreasing complexity varying over time. Feasible work regions compressor stations consisting several turbo compressors included semiconvex approximations a...

The jet propulsion engine is used for the propulsion of aircraft, m issile and submarine (for vehicles operating entirely in a fluid) by the reaction of jet of gases which are discharged rearward (behind) with a high velocity. As applied to vehicles operating entirely in a fluid, a momentum is imparted to a mass of fluid in such a manner that the reaction of the imparted momentum furnishes a pr...

A new dual fuzzy controller for the nonlinear model of the compression system is proposed in this paper. The surge phenomenon in the centrifugal compressor, the non-linearities and uncertainties of the compression system make it impossible to use a conventional controller over a wide range of operation. This fuzzy controller is designed to consist of a active surge control and phase control wit...

Traditionally, process engineers often face the possibility of FEED and detailed engineering designs exceeding limits due to unforeseen circumstances, for example, with complex control systems, operational philosophies and procedures. Potential problems during plant start-up, emergency shutdown and various turndown conditions may not be identified in advance due to insufficient information on p...

Conventional constant speed turbo air centrifugal compressor systems (TACCSs) consist of an electric motor driven at the and inlet guide vane (IGV) for pressure control. TACCSs with inverter a variable drive (VSD) are more efficient than conventional TACCS because they have wide operating range can minimize power consumption. Therefore, this paper proposes quadratic V/f control VSD to reduce el...
