... of atomization are strongly correlated and affect the engine performance. In this study, proper orthogonal decomposition (POD) was applied on spatiotemporally resolved images to characterize Viscor, here used as diesel surrogate, and methanol sprays of pressure-swirl atomizers employed in Siemens Energy...

... the development of low-emissions technologies. Atomization modeling is often facilitated by using the Lagrangian approach rather than the more complex and computationally expensive Volume-of-Fluid (VOF) approach. However, most Lagrangian breakup models rely on empirical constants that must be fully calibrated...

...Brandon Esquivias; Brendan Hickey; Vincent McDonell; Soichiro Tabata; Shigeki Senoo The breakup of liquid films in high-speed flows is found in many applications. These include prefilming air blast atomization found in fuel injectors and shedding of droplet off of airfoils. In this work, a test rig...

...Huu P. Trinh; C. P. Chen; M. S. Balasubramanyam This paper describes numerical implementation and validation of a newly developed hybrid model, T-blob/T-TAB, into an existing computational fluid dynamics (CFD) program for primary and secondary breakup simulation of liquid jet atomization...

...Ashraf A. Ibrahim; Milind A. Jog Predictions of breakup length of a liquid sheet emanating from a pressure-swirl (simplex) fuel atomizer have been carried out by computationally modeling the two-phase flow in the atomizer coupled with a nonlinear analysis of instability of the liquid sheet...
