... to the pitch lines of A-type and that of B-type are defined as compression chambers of A-series and B-series, respectively. Then the general geometrical model of scroll compression chamber is set up. It can demonstrate the deforming, opening, and vanishing process of all scroll chambers. Effective turns...

... cavitation jet that plastically deforms the surface, imparting compressive residual stresses. The process developed involves injection of a high-speed oil jet ( ∼ 230 m / s ) through a suitably designed nozzle, into an oil-filled chamber containing the specimen to be peened. The region of cavitation...

...Wayne Strasser A moving-deforming grid study was carried out using a commercial computational fluid dynamics (CFD) solver, FLUENT ® 6.2.16. The goal was to quantify the level of mixing of a lower-viscosity additive (at a mass concentration below 10%) into a higher-viscosity process fluid...

... simulations of growth and deformation of a filter cake. Two examples of cake growth and deformation phenomena of interest to the oil industry are the sticking of drill string within a wellbore and the sealing of wellbore sections by expandable packers. The calculation algorithm is based on the algebraic slip...

... of a vortex with a free surface, and the deformation of a cylindrical bubble. Promising agreement with other sources of data is found in every case. A two-dimensional Level-Set method has been developed for the study of violent free surface motion. The main differences between the algorithm described...

... and the deformation parameter characterizing the bubble evolution are critically examined. An excellent satisfaction of the mass conservation requirements is observed in all case studies undertaken. two-phase flow bubbles shear flow deformation A large variety of engineering problems involves...
