The paper presents novel analytical droplet breakup criteria, on Weber number (We)-relative turbulence intensity and We-Ohnesorge (Oh) representations, based on the critical Weber number. The We-Oh...

The solution precursor thermal spraying (SPTS) process is used to obtain nano-sized dense coating layers. During the SPTS process, the in situ formation of nanoparticles is mainly dependent on combustion gas-temperature, gas-pressure, gas-velocity, torch design, fuel type, and Oxygen-Fuel (O/F) mixture ratios, precursor injection feeding ratio and flow rates, properties of fuel and precursor and its concentration, and the precursor droplets fragmentation. The focus of the present work is the num...

Abstract We propose a unified model for the three branches of the explosion limits of an H 2 –O 2 mixture. By using different expressions for the ignition delay time at each limit, and by utilizing the Le-Chatelier rule, we obtain an analytical expression for the ignition delay time of the mixture. We show that by solving the time delay equation for a selected typical ignition delay time we obtain a single expression for the Z-shape explosion limits.

The trilateral cycle (TLC) is one of the most promising alternatives among the heat recovery-to-power technologies, due to its compact system configuration and high performance at relatively low compression work and low-to-moderate expander inlet temperature. These feats make the TLC beneficial for off-grid applications particularly in remote or offshore applications where power-to-weight ratio of the power plant is of significance. This study presents the thermodynamic performance simulation an...

Abstract Starting from the baseline of a Diesel engine, we show that with a suitable in-cylinder catalyst and well controlled injection of fuel and steam mixture during a certain period in the compression stage, a significant increase in the ideal cycle efficiency is achievable (from 67% to 78% for an initial compression ratio of 25). In such an arrangement, the fuel injection session comprises a two-stage process. In the first stage, fuel and water are injected into the hot previously compresse...

Abstract The trilateral flash cycle (TFC) among the heat recovery-to-power technologies presents a great potential for development. Unlike the Rankine cycle, the proposed TFC does not evaporate its working fluid during the heating phase; instead expands it, from the saturated liquid condition, as a two-phase mixture bypassing the isothermal boiling phase. This paper examines the feasibility of interfacing the TFC system for low-grade heat recovery-to-power generation using thermal energy from ho...
