OVERVIEW OF NUMERICAL METHODS FOR SIMULATING RANQUE-HILSCH EFFECT WITHIN VORTEX TUBES / LIETUVOS KARJERŲ UŽPILDŲ POVEIKIO BETONO ŠARMINEI KOROZIJAI TYRIMAI

The main goal of this paper is to present a summarized overview of the methods used for Ranque–Hilsch vortex tube numerical analysis using computational fluid dynamics (CFD). The overview is mainly focused on the most recently conducted studies that are both backed by experimental data and is evaluated by the authors as being in good agreement with experimental results. Generalized tendencies in computational vortex tube analysis are presented while focusing on researchers’ approach towards the geometric model used for the study and the governing equations. A brief introduction to the subject matter is presented followed by a short retrospective of the previous studies and related challenges. The conclusions are formed based on the most recent, as well as previously analysed, published research results
