In this contribution, we address the role of driving forces for enhancing the collisional machine performance. Analytical expressions for thermodynamic quantities such as power output and efficiency are obtained for general driving schemes. A proper choice of these driving schemes substantially increases both power output and efficiency and extends the working regime. Maximizations of power and efficiency, whether with respect to the strength of the force, driving scheme, or both have been considered and exemplified for two kind of drivings: generic power-law and harmonic (sinusoidal) drivings. | Notes: | Fernando, S (corresponding author), Univ Sao Paulo, Inst Fis, Rua Matao 1371, BR-05508090 Sao Paulo, SP, Brazil. | Document URI: | http://hdl.handle.net/1942/38905 | ISSN: | 2470-0045 | e-ISSN: | 2470-0053 | DOI: | 10.1103/PhysRevE.106.044134 | ISI #: | 000877678300007 | Rights: | 2022 American Physical Society | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2023 |
