Sviluppo e validazione di un modello di film fluido per simulazioni CFD di motori a combustione interna
A wall film model has been implemented in a customized version of KIVA code developed at University of Bologna. Under the hypothesis of `thin laminar ow' the model simulates the dynamics of a liquid wall film generated by impinging sprays. Particular care has been taken in numerical implementation …

Simulations And Experiments Of Fuel Injection, Mixing And Combustion In Di Gasoline Engines
… carried out to observe the external spray and wall impingements in an optical constant volume vessel. The fuel film deposit characteristics were derived using the Refractive Index Matching (RIM) technique. Finally, the interactions of sprays with the charge motion are investigated in an optical …

Evaluation of the atomization-based cutting fluid spray system in milling of titanium alloy
… on Discrete Phase Modeling approach and Eulerian Wall Film model, of an ACF spray system has been developed and used to simulate the liquid film formation on a rotating cylindrical surface, to explain the variation in the experimentally observed cutting forces for different combinations of spray …

Modeling of biofuel-diesel multi-component fuel effects on vaporization, micro-explosion and combustion
… vaporization and spray impingement on cylinder walls. Residual fuel in the cylinder causes high levels of unburned hydrocarbons and carbon monoxide emissions while altering engine fuel-oil dilution. Thus, fuel atomization that produces fine droplets is preferred, as it enhances the air-fuel …

Atomized dielectric spray-based electric discharge machining (spray-EDM) for sustainable manufacturing
… dielectric droplets form a moving dielectric film up on impinging the work surface that penetrates the inter-electrode gap and acts as a single-phase dielectric medium between the electrodes. It also effectively removes the debris particles from the discharge zone. Single-discharge EDM …

Development of particle-scale simulation methods for multiphase flow study
… and interactions of fuel drops and heated walls.</p> <p>The first topic is the fast pyrolysis of biomass materials, an effective means to convert biomass into useful energy products. The conversion process can be significantly affected by the properties of the biomass particle and the …
