3D simulation of droplet impact on static and moving walls
Yılmaz, Anıl; Kayansalçik, Gökhan; Ertunç, Özgür (Begell House Inc., 2022)In the present study, the contact angle model and the origin of the parasitic current, precisely, the relation of the parasitic current with grid distribution, have been studied to accurately predict droplet impact on ... -
Benchmark study of 2D and 3D VOF simulations of a simplex nozzle using a hybrid RANS-LES approach
Bal, M.; Kayansalçik, Gökhan; Ertunç, Özgür; Erhan Böke, Y. (Elsevier, 2022-07-01)In this study, a simplex nozzle is tested with water for the benchmarking of different flow simulation models. A large scale Plexi-glass transparent nozzle is used to reduce the influence of production tolerances on the ... -
The effect of interface gradient distribution on unrealistic flow in 3D droplet simulations
Yılmaz, Anıl; Kayansalçik, Gökhan; Ertunç, Özgür (Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2021-08-31)The purpose of this study is to investigate the origin of the parasitic current to provide accurate prediction of droplet surface interactions in Volume of Fluid (VOF) framework. The deformation of the droplet due to ... -
Validation and comparison of 2D and 3D numerical simulations of flow in simplex nozzles
Bal, M.; Kayansalçik, Gökhan; Ertunç, Özgür; Böke, Y. E. (Europe, Institute for Liquid Atomization and Spray Systems, ILASS, 2021-08-31)Numerical simulations of pressure swirl atomizers are computationally expensive due to transient and multiphase flow behavior. In this study, 2D and 3D VOF simulations are performed for a geomerty which has high swirl ...
