Design and Simulation of an Opposed-Piston Engine Worked by the Resonant and Focusing of the Shock Wave
This paper was carried out a design to produce high-pressure shock-wave forms in order to increase the efficiency
of the energy concentrated by the shock reflection, resonant or focusing. In this study, numerical simulation was adopted to
analyze the interaction between shock waves and moving boundaries. The CFD method is applied to simulate the shock
resonant or focusing in an opposed-piston engine driven by shock wave. The finite volume method for solving Navier-Stokes
equations to investigate the resonant and focusing of the shock wave in a typical cylinder. The test parameters are including
of pressure source, temperature, piston weight and high-pressure release time. This analysis allowed for the identification of
the interdependence among the parameters involved when shock waves are used to concentrate energy. The results of this
study provide a reference for follow-up experiments and future system design of a magnetic-fluid generator.
