Coandǎ Effect

A new gripping principle, based on Coanda effect was applied successfully in designing and developing a non contact robot gripper to curb the gripping challenges faced in the food industries. Two designs of the non contact grippers/ejectors which are working on Coanda effect are presented in this paper. The first design was made with one suction head while the second design was made with multiple suction heads. Experiments were carried out on both ejectors to observe their holding force on food materials as a function of mainly the pressure, flow of the primary air and other parameters. Tangible results were derived from the experiments, tabulated and shown in graphical forms; from which relationships between the parameters were derived. When tested on thick bark/packed food materials, they left no suction marks on them.

Coandǎ Effect

The present work is focused on the study of an innovative fluidic device. It consists of a two-ways diverter valve able to elaborate an inlet water flow and divert it through one of the two outlets without moving parts but as a result of a fluctuation of pressure induced by two actuation ports, or channels. Such apparatus is named Attachment Bi-Stable Diverter (ABD) and is able to work with the effect of the fluid adhesion to a convex wall adjacent to it, this phenomenon is known as Coanda Effect; it generates the force responsible for the fluid attachment and the consequent deviation. The main purpose of this work is to develop a knowhow for the design and development of such particular device. A mathematical model for the ABD has been developed and used to find the relationships between the geometrical parameters and the operative conditions. A configuration has been designed, simulated with a computational fluid dynamics approach. A prototype has been printed with and additive manufacturing printer and tested in laboratory to check the effective working point of the device.
