29 In the model, particles inside the spray zone receive an amount of spray based on the solid fraction and position of the particles. A Bi-conical spray zone is used in the work of Börner et al.30 to model various spray granulators. They validated their model by comparing the ...
To clarify the fuel spray formation process for a swirl-type injector, numerical analyses using both VOF (Volume Of Fluid) model and DDM (Discrete Droplet Model) method are carried out. VOF model is used to simulate the two-phase flow inside the injector and also the liquid film formation ...
H Cao,L Zhang,HUANG Wenqian,S Jia,X Liu 摘要: Aiming at the problem that digital depth model( DDM) for non-navigation can't be directly applied to navigation,a method of the transformation from DDM for non-navigation to navigation based on the fitting surface of depth uncertainty is ...

Considering the complexity of the mechanical properties of the structural plane, it is generally simplified in numerical model, usually adopting rigid or linear deformation model[3,5], but the linear deformation model could not precisely reflect its actual physical and mechanical properties, several ...
Moreover, Brute Force method indicates a larger impacting area, and it brings discrete negative points and some of these points are close to large positive numbers, indicating numerical errors in the model calculation. In comparison, the DDM-3D results are more reasonable. 展开 关键词:...
