Evaporation of n-decane with solid additive under different affecting conditions

The quest for enhancing the evaporation efficiency of hydrocarbon fuels through the utilization of solid-additives has garnered substantial attention in the realm of energy research. This article presents a comprehensive numerological investigation into the evaporation dynamics of hydrocarbon fuels, specifically when mixed with solid-additives. By integrating mathematical modeling and empirical analysis, this study elucidates the complex interplay between solid-additive properties and the evaporation process of hydrocarbon fuels. This paper is conducted with n-decane/Aluminum droplets at various affecting conditions such as initial solid concentrations, ambient pressures, and temperatures. As mentioned, this study adopts a multifaceted analysis approach, rather than analyzing the impact of additive particle concentration and ambient conditions, it also investigates the effects of droplet diameter, droplet velocity relative to ambient, and different solid-additive elements on the different aspects of the evaporation process. The findings, not only shed light on the underlying mechanisms governing the evaporation of solid-laden hydrocarbon fuels but also pave the way for developing more efficient and environmentally-friendly fuel blends. The findings demonstrate that solid-additive particles can significantly influence the evaporation characteristics of n-decane, with higher concentrations prolonging the drying process. Additionally, ambient pressure and temperature, droplet diameter and relative velocity, and fuel vapor concentration in the ambient gas also play crucial roles in the evaporation dynamics. The evaporation process does not follow the d2-law, lower pressure, temperature, larger diameter, higher relative velocities, and lower fuel vapor concentration in ambient enhance evaporation rate while accounting for these effects is essential for optimizing the related processes.
