Design, simulation, and validation of additively manufactured high-temperature combustion chambers for micro gas turbines

simulation and design of electronic processing circuit for restaurants e-procurement system

the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

High Temperature Materials for Gas Turbines: The Present and Future

Increased operating temperatures and higher efficiency in gas turbines and jet engines can reduce CO2 emission, thus contributing to the prevention of global warming. To achieve this goal, it is essential to improve the properties of high temperature materials. Various Ni-base superalloys are used for high-temperature components, e.g., combustors and high-pressure turbine blades and vanes, that...

Additively manufactured hierarchical stainless steels with high strength and ductility.

Many traditional approaches for strengthening steels typically come at the expense of useful ductility, a dilemma known as strength-ductility trade-off. New metallurgical processing might offer the possibility of overcoming this. Here we report that austenitic 316L stainless steels additively manufactured via a laser powder-bed-fusion technique exhibit a combination of yield strength and tensil...

Modelling and simulation of gas turbines

Today, gas turbines (GTs) are one of the major parts of modern industry. They have played a key role in aeronautical industry, power generation, and main mechanical drivers for large pumps and compressors. Modelling and simulation of GTs has always been a powerful tool for performance optimization of this kind of equipment. Remarkable research activities have been carried out in this field and ...
