【 摘 要 】

Born more than a century ago, the concept of exploiting the pressure wave phenomenon has evolved with rather small steps, experiencing an accelerated progress over the past decades. This paper aims an overview on the researchers' results over time regarding the pressure wave technology and its applications, pointing out on the internal combustion engine's supercharging application. This review complements the past reports on the subject, presenting the evolution of the concept and technology, as well as the researcher's efforts on solving the specific shortcomings of this pressure wave technology. Undoubtedly, the pressure wave rotors have been a research goal over the years. At first, most of the researches were experimental and the theoretical calculations required to improve the technology were too arduous. Recently, new computer software dedicated to accurate simulation of the processes governing the wave rotor operation, altogether with modern experimental measurement instruments and well-developed diagnostic techniques have opened wide possibilities to innovate the pressure wave supercharging technology. This paper also highlights the challenges that specialists still have to overcome and aspects to become future preoccupations and research directions.
