Micro Gas Turbines (MGTs) are nowadays largely used for electrical and thermal energy production in small buildings households. Their reliability compactness allow them to operate thousands of hours with minimal maintenance. However, the long exposure at high temperatures combustion chambers can promote creep, which induce fatigue potential failure these components. Creep-induced damage MGTs ha...

Coal is a combustible material applicable to a variety of oxidation scenarios with conditions ranging from atmospheric temperature to ignition temperature. One of the most frequent and serious causes of coal fires is self-heating or spontaneous combustion. Opening an underground coal seam to mine ventilation air, such as long-wall gob and goaf areas and coal stockpiles, creates a risk of sponta...

This paper presents a research work to develop a navigation technique for a class of nano-micro space rocket. Onboard MEMS inertial sensors are used in view of post-flight trajectory estimation. Combined with synchronized measurements of the combustion engine which is of hybrid type and uses N2O and PE, we show how the relative redundancy of the data can be used to calibrate a thrust model. Exp...

With ever increasing concern on oil prices and energy conservation, there is a fast growing interest in hybrid vehicles globally. Currently, all hybrid vehicles, including micro, mild and full hybrids, adopt internal combustion engines which are inefficient in general. The corresponding waste heat of exhaust gas constitutes up to 40% of the fuel consumption. So, it is a pressing need for resear...

recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. a number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working hypo...

in this paper, a hybrid solid oxide fuel cell (sofc) and micro gas turbine (mgt) power system is parametrically studied to evaluate the effect of different operating conditions. the sofc/mgt power system includes sofc reactor, combustion chamber, compressor and turbine units, and two heat exchangers. the effects of fuel utilization, temperature, and pressure are assessed on performance of the h...
