Droplet evaporation in a turbulent high-pressure freestream – A numerical study

A Hydrocarbon Droplet Evaporating in Turbulent Environment at Elevated Ambient Pressure and Temperature

“…A recent publication by the present author was the first to report realistic experimental data (Birouk and Fabbro, 2013). Pertaining literature was recently reviewed by the present author and coworkers (Birouk and Abou Al-Sood, 2010;Birouk and Fabbro, 2013;Birouk et al, 2008). The present work, which is a continuation of these efforts, reports new experimental data on the vaporization process of hydrocarbons droplet in a turbulent environment at elevated ambient pressure and temperature conditions.…”

“…This is mainly due to the lack of data and knowledge on the impact of gas phase turbulence on the droplet gasification, especially under realistic test conditions of ambient pressure and temperature. Although, recent numerical simulations were carried out to gain insight on the effect of turbulence on the droplet vaporization process at high pressure and temperature conditions (e.g., Birouk et al, 2008;Birouk and Abou Al-Sood, 2010), it is still difficult and costly to develop test rigs capable of replicating test conditions of practical relevance. A recent publication by the present author was the first to report realistic experimental data (Birouk and Fabbro, 2013).…”

Simple Model for Low Intensity Turbulence Effects on the Vaporization of Liquid Single Droplets in Forced Convective Conditions

“…Finally, all the thermophysical properties of liquid and vapor are calculated from references [19,20], and the vapor-air mixture properties (denoted with subscript "g") are evaluated using the reference temperature and fuel concentration, i.e. equations (12,13), where Ar=1/3 refers to the widely used film conditions.…”

“…The review carried out in [3] showed that most of the available published works on turbulence effects on droplet vaporization in forced convective flows [4][5][6][7][8] or in zero-mean velocity turbulent flows [9][10] are experimental. Some numerical studies are available in the open literature [11][12][13][14][15][16]. The main conclusion is that turbulence enhances the evaporation process of droplets.…”

A theoretical study of the spheroidal droplet evaporation in forced convection

“…75 Most of the current theoretical models were developed for a spherical droplet. 76 However, a non-static droplet tends to deform especially at high value of Reynolds 77 number [7][8]. Experiments The droplet shape is described as oblate spheroid along with the evaporation process.…”
