Spray atomization is a common process found in different industries, where sprays under high injection pressure are widely recorded in the literature. Nonetheless, research on spray breakup mechanism under low pressure in pharmaceutical industry is still relatively rare. Numerical model in the Lagrangian approach was modified for simulating the spray formation from a nasal spray device in the c...

Background & Aims: Nanosilver-based paint is a new technology with antimicrobial and antifungal characteristics. These characteristics were investigated in this study with regard to fungal contamination in hospitals. Method: Regarding hospitalization of transplant patients and their sensitivity to hospital infections, two similar rooms were selected in nephrology ward. One of them was paint...

This paper investigates the use of several common objects such as spray cans, ashlights, carving knives, and others as metaphors for visualization. The motivation behind this work is to provide an intuitive and natural 3D interface such that users will view these objects as tools during the visualization process. To help achieve this goal, the selection of the object tools are derived from expr...

METAL transfer describes the process of the molten metal movement from the electrode tip to the workpiece in gas metal arc welding (GMAW). A better understanding of the metal transfer process is important for improvements in the quality and productivity of welding. While several distinct modes of the metal transfer have been classified,[1] the globular and spray transfer modes have received att...

Technical development and commercial implementation of the supercritical fluid spray process have produced the surprising result that coating appearance and performance can actually be improved by removing 60 to 80 percent of the organic solvent from solvent-borne coating formulations. Unlike normal diluent solvents and water, the decompressive release of supercritical carbon dioxide during spr...

Abstract This perspective paper summarizes the authors’ view on how process diagnostics and control can help to gain a deeper insight into thermal spray processes better understand underlying mechanisms. The current situation in terms of available strategies suitable sensors is described. In perspective, it assumed that with models, machine learning tools, will be possible perform smaller numbe...
