Modeling of Evaporation Process of Multicomponent Fuel Spray

Continuous Thermodynamics Finite Diffusion Model for Multicomponent Fuel Spray Evaporation

INTRODUCTION The different volatility of the components of a fuel mixture will result in different vaporization rates of components at the droplet surface, and the fuel becomes non-uniform inside the liquid phase because of the mass diffusion resistance inside the droplet. For practical, multidimensional simulations of IC engines, zero-dimensional models for the liquid phase are necessary becau...

Modeling of a dilute vaporizing multicomponent fuel spray

A simplified spray environment is used to represent the multicomponent nature of liquid fuels and to examine the sensitivity of their vaporization behavior to the various liquidand gas-phase models. Liquid-phase models are the diffusion limit, the infinite diffusion, and the vortex. Gas-phase models are the Ranz-Marshall correlation and the axisymmetric model. Three subsets of equations are sol...

مطالعات و بررسی های انجام گرفته نشان می دهد ترکیبات بودار موجود در ‏‎fuel oil‎‏ عمدتا ترکیبات سولفوردار سخت مثل تیوفن، دی متیل بنزوتیوفن و ... بوده و روشهای بوزدایی همچون استخراج با حلالهای اسیدی و بازی ، رقیق کاری با گازولین ، ماسکینگ با بوتیل استات نتایج چندان مطلوبی در بوزدایی از آن نشان نمی دهند.همچنین روش جذب سطحی برای بوزدایی ‏‎fuel oil‎‏ تنها با استفاده از جاذب هایی همچون بنتونیت و توفیت...

CFD modeling and analysis of brine spray evaporation system

A spraying evaporation system applied to brine disposal is reported, which is mainly used for disposing the brine with concentration more than 100,000 mg/L. A computational fluid dynamics (CFD) simulation has been carried out to study the brine droplet evaporation and diffusion process in high temperature air flow. A discrete-phase model in spraying evaporation system is developed and a simulat...
