TL;DR: In this article, the effect of using different biofuel blends on gas turbine emissions and performance was studied in a can type combustor at two different operating conditions and the performance of the combustor was evaluated by determining the combustion efficiency, temperature rise, and the emission indices.

TL;DR: In this paper, the authors used the assumed shape multi-environment Eulerian PDF Transport method (MEPDF), which involves representing the joint composition PDF shape as a collection of finite number of Delta functions, to model the turbulence-chemistry interactions.

TL;DR: In this paper, the results of an experimental study of a twin-fluid internally mixed swirl atomizer were presented, where the atomization is attained by injecting a small amount of air (i.e. of the order of less than 16% of the mass flow rate of liquid) into a liquid stream within the injector and the two-phase air liquid mixture is passed through a swirling passage to impart a swirling motion to the flow.
Abstract: This paper presents the results of an experimental study of a twin-fluid internally mixed swirl atomizer. In this type of injectors, atomization is attained by injecting a small amount of air (i.e. of the order of less than 16% of the mass flow rate of liquid) into a liquid stream within the injector and the two-phase air liquid mixture is passed through a swirling passage to impart a swirling motion to the flow. Since most of the energy for atomization is supplied to the liquid by the atomizing air, a significantly small pressure drop can produce very fine spray with a small amount of atomizing air. At low values of air–liquid mass ratio (ALR), the appreciable tangential component of velocity with respect to the axial velocity provides a hollow cone spray structure, which turns into a solid cone spray with the increase in axial momentum, through either an increase in ALR or the liquid supply pressure. The results presented in this paper suggest that the investigated injector could be used to control the flow rate and spray characteristics (e.g. spray cone angle, spray solidity, breaking distance, and the droplet diameter) independent of each other by simultaneously varying the supply pressure of the liquid and the atomizing air flow rate. The controlled atomization studied in this paper for a twin-fluid internally mixed swirl atomizer makes it attractive to be used for various commercial applications as the atomizer is capable of providing various spray characteristics depending upon the application requirement.

TL;DR: In this paper, an experimental study of the effect of injector's geometry on the performance of an internally mixed, air-assisted, liquid injector is presented, showing that the size of the droplets produced by the investigated injector decreases with a decrease in the air injection area.

TL;DR: In this paper, the authors proposed the Detached-Eddy Simulation (DES) approach and large-scale Eddy Simulation approaches (LES) approaches to simulate the environment.
Abstract: 应用DES(Detached-Eddy Simulation)方法数值模拟了3种不同失速类型的翼型的升力特性.DES方法结合了RANS(Reynolds-averaged Navier-Stokes)和LES(Large Eddy Simulation approaches)的优点.基于Spalart-Allmaras湍流模型,在近壁面DES体现为RANS模型的特点而在远离物面处又具有LES的亚格子模型的特性.对此模型使用了LU-SGS隐式格式求解.通过和实验结果对比,显示这种方法可以有效地预测翼型的失速特性.
