Steady State Analysis of Nanofuel Droplet Evaporation
The potential for nanofuels as one of the clean sources of energy on account of its enhanced combustion performance coupled with low emissions has been established. Considering the importance of the fuel evaporation phase in the entire combustion process, this work presents an attempt at applying the steady state analysis equations to nanofuel experimental data obtained from the li...
متن کاملEvaporation of a Liquid Droplet
Two idealized models for the preheat s tage of liquid droplets are ana lyzed theoretically . These models conta in the effects of transie nt heat conduction and evaporati on. It is assumed that the droplet surface a rea decreases linearly with time. This assumption necessitates the solution of mov ing boundary problems . These models, however, do not consider gas-phase mass transport . In the f...
متن کاملComparative Analysis of a Single Fuel Droplet Evaporation
In this research, the results of comparative analysis of a single fuel droplet evaporation models are presented. Three well-known evaporation models including Spalding, Borman-Johnson and Abramzon-Sirignano models are analyzed using Computational Fluid Dynamic (CFD). The original Spalding model is extended to consider the effects of the Stefan flow, unsteady vaporization, and variable propertie...
متن کاملDroplet evaporation on a horizontal substrate under gravity field by mesoscopic modeling.
The evaporation of water drop deposited on a horizontal substrate is investigated using a lattice Boltzmann method (LBM) for multiphase flows with a large-density ratio. To account for the variation of evaporation flux distribution along the drop interface, a novel evaporation scheme is introduced into the LBM framework, and validated by comparison with experimental data. We aim at discovering ...
متن کاملModeling Cryogenic Spray Temperature and Evaporation Rate Based on Single-Droplet Analysis
Cryogenic sprays are of interest in dermatology for cooling human skin during pulsed laser treatment of port wine stain (PWS) birthmarks. In the present study, a Phase Doppler Interferometer (PDI) was used to obtain preliminary measurements of mean diameters and mean velocities of tetrafluoroethane (HFC-134a) spray droplets, generated by an atomizing nozzle of a commercial dermatological instru...
