Bubble-Bursting Atomization for Minimum Quantity Lubrication Using the TRIZ Method and Computational Fluid Dynamics Simulations

This present study explored using minimum quantity lubrication (MQL) as a sustainable solution for machining. A bubble bursting atomization (BBA) system was created using theory of inventive problem solving (teoriya resheniya izobretatelskikh zadach, TRIZ) and computational fluid dynamics (CFD) simulations. TRIZ was chosen as it offers problem-solving tools as well as aids in problem identification and innovative design. Various TRIZ tools, such as function analysis and cause-and-effect chain analysis, were employed to design the BBA system. The proposed BBA chamber was designed to produce nano-aerosols (NAs), thereby, increasing the lifespans of cutting tools. Computational fluid dynamics (CFD) simulations and structural analysis confirmed that it was safe to fabricate a prototype of the stainless-steel BBA chamber. The proposed BBA-MQL system outperformed commercial MQL (Comm.-MQL), as it improved the lifespans of cutting tools at a cutting speed (A) of 300 m/min.
