Modelling of the Multicomponent Droplet Vaporization
Author: Virginel Bodoc
Publisher:
ISBN:
Category :
Languages : en
Pages : 54
Book Description
The objective of this thesis was to study the vaporization of a multicomponent spray with both experimental and numerical approaches. To achieve this objective, the effort was guided in two directions. Firstly, an experimental database has been created using different optical measurement techniques. A special attention was focused onto the application of Global Rainbow Refractometry (GRR), used for the measurement of droplets temperature. Secondly, numerical simulations were performed for mono and bi-component sprays in evaporation. In the first part of this study, experimental and numerical tests were carried out on a polydisperse nonconfined and cooling spray. This configuration was adopted because it allows the study of the vaporization with a reduced influence from the gaseous phase. For a bi-component liquid, the effect of the composition variation on the GRR measurements was analysed within a coupling between the experimental technique and the numerical simulation. In the second part, experimental investigations and numerical simulation were performed for a more complex configuration that consists in a spray evolving in a heated and confined medium. The gaseous phase was computed with a LES approach while the dispersed phase, always mono-component, was solved with a Lagrangian tracking approach . The unsteady nature of the flow was demonstrated and the interest of the GRR technique for the droplets temperature measurement was proved.

Heating and Evaporation of Multi-Component Fuel Droplets
Author: Mansour Al Qubeissi
Publisher: BoD – Books on Demand
ISBN: 3955380238
Category : Technology & Engineering
Languages : en
Pages : 302
Book Description
This book documents pioneering mathematical models introduced for the simulation of multi-component droplets heating and evaporation processes which are implementable into commercial CFD codes. These models, described as 'multi-dimensional quasi discrete' (MDQD) and 'discrete-component' models, were applied to automotive fuel droplets in experimentally measured internal combustion engine conditions for biodiesel, diesel, and gasoline fuels. For instance, it is shown that the suggested models lead to accurate predictions of temperatures and evaporation times in typical diesel and gasoline engine conditions. Such models have also reduced CPU time about 85% compared with cases when classical approaches are used.
