Automated flow rate control of extrusion for 3D concrete printing incorporating rheological parameters
Ahi, Oğulcan; Ertunç, Özgür; Bundur, Zeynep Başaran; Bebek, Özkan (Elsevier, 2024-04)The use of inline quality assessment technologies is of great importance in meeting the consistent extrusion requirements of 3D concrete printing (3DCP) applications. This paper presents a system to regulate extrusion speed ... -
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 ...
