Droplet evaporation characteristics due to wet compression under RCM conditions

Gas-phase saturation and evaporative cooling effects during wet compression of a fuel aerosol under RCM conditions

“…This study utilizes the wet compression model described previously by Johnson et al [16]. The model integrates a fully transient evaporation model developed by Aggarwal and co-workers [17][18][19] with a gas-phase volumetric compression model.…”

“…Application of the integrated model to study wet compression of an isolated droplet has been described in Ref. [16]; however there is currently a lack of experimental data for validation of the integrated wet compression model. In Ref.…”

“…In Ref. [16] other approaches for modeling wet compression are reviewed and compared. It was demonstrated in that work that simplified models, such as quasisteady formulations, result in significant discrepancies (e.g., +50% in total evaporation time) compared to the results predicted with the fully transient formulation used here.…”

“…[16] in order to investigate droplet-droplet interactions, especially fuel saturation and evaporative cooling effects under RCM conditions. Figure 1 illustrates the configuration implemented in the model for this study.…”

Exergy Analysis of Overspray Process in Gas Turbine Systems

“…Utamura [15] showed experimentally that 1% of injection ratio in wet compression leads to 8% increase in power delivery. Wet compression in gas turbines has been thoroughly investigated by many researchers as Zheng et al [16], White and Meacock [17], Kim and Perez-Blanco [18], Perez-Blanco et al [19], Bracco et al [20], Roumeliotis and Mathioudakis [21], Jonsson et al [22], Goldborough et al [23]. Kim et al [24] developed a modeling for the transient operations for the non-equilibrium wet compression process based on droplet evaporation and obtained the analytic expressions with algebraic equations as solutions.…”
