Mean value first principle engine model for predicting dynamic behaviour of two-stroke marine diesel engine in various ship propulsion operations

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2022
Analysis of ship propulsion system performance is often performed using detailed hydrodynamic models to assess load changes, which are subsequently compared to static engine limits, or by detailed engine models that are rarely integrated with ...

Heat Bath Algorithmic Cooled Quantum Otto Engines [PDF]

open access: yesPhys. Rev. E 100, 012109 (2019), 2019
We suggest alternative quantum Otto engines, using heat bath algorithmic cooling with partner pairing algorithm instead of isochoric cooling. Liquid state nuclear magnetic resonance systems in one entropy sink are considered as working fluids. Then, the extractable work and thermal efficiency are analyzed in detail for four-stroke and two-stroke type ...

CFD Analysis of 2-Stroke Engines

open access: yesEnergy Procedia, 2015
Abstract1d and 3d CFD simulation is a standard engineering practice on 4-stroke engines. However, the application to the 2-Stroke cycle is not so trivial, in particular the transition from detailed CFD-3d analyses to simplified 1d engine simulations. A first critical issue is the correlation between the instantaneous cylinder gas composition and the ...

Two-stroke Quantum Measurement Heat Engine [PDF]

open access: yesarXiv, 2022
We propose and analyze the theoretical model for a two-stroke quantum heat engine with one of the heat baths replaced by a non-selective quantum measurement. We show that the engine's invariant reference state depends on whether the cycle is monitored or unmonitored via diagnostic measurements to determine the engine's work output. We explore in detail

Revealing the strokes of autonomous quantum heat engines with work and heat fluctuations [PDF]

open access: yesPhys. Rev. A 101, 010101 (2020), 2019
We analyze an autonomous thermoelectric engine composed of two superconducting qubits coupled to separate heat baths and connected by a Josephson junction. Work and heat are process quantities and not observables of the engine quantum system, but their rates can be derived from the steady state expectation value of appropriate system observables and ...
