“…They obtained exergetic efficiency of 77.2%, 73.4%, and 69.7% for aforesaid hydrogen concentrations. Bellini and Lu [100] studied the efficiency in terms of availability of power device operated by detonation wave. The second law or exergetic efficiency was computed based on the fuel availability and results are then compared with the exergetic efficiency applied to deflagration system.…”

Pulse detonation engines (PDEs) are new exciting propulsion technologies for future propulsion applications. The operating cycles of PDE consist of fuel-air mixture, combustion, blowdown, and purging. The combustion process in pulse detonation engine is the most important phenomenon as it produces reliable and repeatable detonation waves. The detonation wave initiation in detonation tube in practical system is a combination of multistage combustion phenomena. Detonation combustion causes rapid burning of fuel-air mixture, which is a thousand times faster than deflagration mode of combustion process. PDE utilizes repetitive detonation wave to produce propulsion thrust. In the present paper, detailed review of various experimental studies and computational analysis addressing the detonation mode of combustion in pulse detonation engines are discussed. The effect of different parameters on the improvement of propulsion performance of pulse detonation engine has been presented in detail in this research paper. It is observed that the design of detonation wave flow path in detonation tube, ejectors at exit section of detonation tube, and operating parameters such as Mach numbers are mainly responsible for improving the propulsion performance of PDE. In the present review work, further scope of research in this area has also been suggested.

“…pressure rise, outlet temperature, fuel mass flow and purge fraction). In previous studies the proposed methodology has been successfully applied to estimate the performance of single-tube air-breathing pulse detonation engines [12,13] and to perform an exergy analysis on a stationary gas turbine architecture powered by a pulse detonation combustor [20]. In this study, the application of the methodology is further extended to analyze turbofan aeroengines incorporating a pulse detonation core.…”

“…[1,2] In aerospace application, systems exergy has mainly been applied to aircraft design, analysis, and optimization. It has been applied in various system contexts including lunar base thermal energy designs [3], aircraft system design [4,5,6,7], analysis, and optimization, aircraft engine analysis [8,9,10,11,12], aircraft environmental control [13], pulsed detonation power devices [14], and hypersonics [1,15]. Interesting comparisons between exergy S balance equation and the Breguet range equation have also been done for aircraft [16].…”

System Engineering of launch vehicles and spacecraft is a challenging and complex under taking. There are many diverse systems which must be integrated and balanced to produce an effective design. This involves a multiplicity of individual engineering relationships that are difficult to integrate and even more difficult to define in a best balance. Integration efforts involve many different approaches from process management to mass balance. But these approaches either do not directly address the launch vehicle or spacecraft performance or require many adjustments to be made to discover a balance. The system integrating physics, derived from the fundamental physics of the system, is the key to identifying a fully integrated system performance measure. Launch vehicles and spacecraft are thermodynamic systems with performance defined by thermodynamic properties. Thus, thermodynamic exergy, which integrates all of the systems thermodynamic properties, provides the system integrating relationships. This provides a basis for determining the most efficient design from among many different configuration options and for guiding the design activities from an integrated system level. This paper explores the current physics relationships used in launch vehicle system design and demonstrates that thermodynamic exergy provides a more explicit and complete approach to system integration.
