Secondary fuel jet strategies on mixing enhancement performance of rocket-based combined cycle engine

A Study on Performance of Solid Oxide Fuel Cell-Stirling Engine Cycle Combined System- Part I: SOFC Simulation by Programming in Matlab and Modeling in Hysys

In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...

Experimental and CFD Studies on the Effect of the Jet Position on Mixing Performance

Investigation of Dual Fuel Diesel Engine With Particular Reference to Engine Cycle Model

In order to use gaseous fuels in Diesel Engines, Dual-Fuel Diesel Engine (D. F. D. E) the pilot injection approach is chosen. To predict its performance, an engine cycle model, based on limited-pressure Diesel cycle, is constructed. The model predicts D. F. D. E performance with LPG, and CNG gases. Comparing with pure Diesel engine, by increasing gas proportion in dual-fuel, indicated power and...

Preliminary Design of a Pulsed Detonation Based Combined Cycle Engine

* Member Technical Staff † Vice-President ‡ Professor and Chairman £ Professor Abstract Results of a recent investigation in the design of a single flow path combined cycle engine using periodic detonation waves are presented here. Four modes of operation are used in a sample SSTO trajectory in this preliminary design (sketched in Fig. [1]): (1) An ejector augmented pulsed detonation rocket for...

Investigating the effects of fuel injection strategies in a dual-fuel diesel-H2 compression ignition engine

In this computational research, the separate and simultaneous impacts of diesel direct injection timing, fuel spraying cone angle, and hydrogen gas addition on combustion characteristics, output emissions, and performance in a single-cylinder direct injection diesel engine was studied. In order to conduct the simulations, valid and reliable models for combustion, break-up, and for turbulence wa...
