The physicochemical characteristics of vegetable oils, the atomization and particle size spray are fundamental aspects for simulation their combustion on burners.
 In this study, influence temperature pressure disintegration jet jatropha oil its mixture with gas was simulated a Riello Gulliver burner power ranging from 22.5 to 35.6 KW. dispersion conditions droplets were determined using a...

In this work, we report an original experimental approach for measuring the two-dimensional distribution of the droplets Sauter Mean Diameter (SMD) using the SLIPI-LIF/MIE technique. A hollow-cone spray is formed by continuously injecting water mixed with a non-toxic fluorescing dye at 20 bars injection pressure. The spray is illuminated using a continuous wave laser. The illumination wavelengt...

The combination of emulsified diesel and low temperature combustion (LTC) technology has great potential in reducing engine emissions. A visualization study on the spray and combustion characteristics of water emulsified diesel was conducted experimentally in a constant volume chamber under conventional and LTC conditions. The effects of ambient temperature on the evaporation, ignition and comb...

Atomization of liquid fuel controls combustion efficiency and pollutant emissions of internal combustion engines and gas turbines (Lefebvre 1998). The liquid jet in crossflow (LJCF) finds application in lean premixed prevaporized (LPP) ducts, afterburners for gas turbines, and combustors for ramjets and scramjets. This flow configuration, which consists of a turbulent liquid jet injected transv...

The effects of polydispersity on radiative and interfacial convective heat transfer are investigated in particle–gas two-phase media for solar particle receiver applications. Non-grey is analysed using the collision-based Monte Carlo ray-tracing method. Mie theory employed to calculate properties particles. finite volume method explicit Euler time integration scheme used solve transient energy ...

Experimental studies have revealed that the introduction of a small amount (0.5% by volume) permanent and chemically inert gas bubbles leads to intensification droplets disintegration in liquid–liquid system (emulsification) pulsating flow type apparatus. The liquids used were water (continuous phase) oil (dispersed at room temperature, nitrogen was as gas. hold-up φin varied range 0% 4%. volum...

Abstract Purpose As documented by multiple studies, the construction of artificial reservoirs influences fluvial processes. The hydrographic barrier causes a water regime change, and effects are evident in accumulation sediment reservoir as well intensification erosion process below dam due to lack sediments for transport river. Moreover, use lateral canals on additional transformations river s...
