 A multizone model of the combustion chamber dynamics in a controlled trajectory rapid compression and expansion machine (CT-RCEM)Abhinav Tripathi, Chen Zhang and Zongxuan Sun Applied Energy, 2018, vol. 231, issue C, 179-193 Abstract: A novel, controlled trajectory rapid compression and expansion machine (CT-RCEM) with the unique capability of precise motion control of the piston has been developed. The compression and expansion profile can be varied, in the CT-RCEM, by digitally changing the piston reference trajectory assigned to the active motion controller. Besides the ease of operation, and wider selection of operating parameters with higher resolution, this capability lowers the turnaround time between experiments by eliminating the need for any hardware intervention. More importantly, this capability allows us to tailor the thermodynamic path of compression (and expansion) – essentially the pressure and temperature profile – by appropriate selection of the piston trajectory. However, to effectively leverage these features of the CT-RCEM, a numerical model is essential – for selection of appropriate thermodynamic path for chemical-kinetic investigations, as well as for the interpretation of the corresponding experimental results.
