Limp materials like textiles, leather, porous tissues, meat and fish fillets do represent challenges in automation. A universal gripping principle that is usable for all these materials is not known. This paper describes a new gripping principle based on a novel Coanda effect ejector meeting these challenges. This ejector allows the construction of a slim, plate-shaped vacuum gripper with multi...
Coanda Effect in Mechanical ventilators: Named after Henri Marie Coanda (June 7, 1886 – November 25, 1972) was a Romanian inventor, aerodynamics pioneer and the patent holder of the modern jet aircraft. The secret of the fluidic flip is a phenomenon known as the Coanda effect. This is a relatively new discovery previously applied in the fields of aerodynamics and jet engine design. When a jet o...
This work investigates the ability of Coanda jet blowing to modify the base pressure of a cylindrical body aligned axially in a flow, and thereby, produce overall drag reduction. It is found that blowing through one or two slot jets concentric to the outer body circumference can significantly influence the entire base flow region. The recirculating wake is eliminated and is replaced by freestre...
In recent years the demand for Unmanned Aerial Vehicles (UAV's) has increased rapidly across many different industries and they are used for various applications. Such systems have the ability to enter dangerous or inaccessible environments and allow vital information to be collected without human risk. In order to carry out a task, a UAV has to face many different challenges. This has led to t...
There is an increasing need to screen water in surface water collection systems to remove floating debris and small aquatic organisms to protect receiving water bodies. Recently, the Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA, New Mexico, USA) has actively introduced structural debris removal from storm-water facilities as a best management practice. In the South Diversion ...
Mitral valve regurgitation (MR) is a disorder of the heart in which the mitral valve does not close properly. This causes an abnormal leaking of blood backwards from the left ventricle into the left atrium during the systolic contractions of the left ventricle. Noninvasive assessment of MR using echocardiography is an ongoing challenge. In particular, a major problem are eccentric or Coanda reg...
