It can be observed in the LIF image at 570 degCA (Figure 8a) that the Coanda effect
manifests itself immediately after SOI as the jet is deflected to the pent roof instead of proceeding along the injector axis to form a hollow cone.
To combat the Coanda effect
, engineers used ANSYS Workbench to parametrically experiment with different inlet and outlet nozzle designs, all geared toward reducing losses, accelerating flow and diverting it away from tunnel walls to reduce aerodynamic friction.
The supply of inlet jets creates plane jets to both sides of the beam that normally attach to the ceiling, utilizing the Coanda effect
The YC-15 introduced a number of innovative features, such as externally blown flaps, which used double-slotted flaps to direct part of the jet exhaust downwards, while the rest of the exhaust passed through and downward over the flaps, introducing the Coanda effect
The new product features an air compression chamber that makes use of the Coanda effect
principle to collect air as it leaves the blowers and compress it into a concentrated stream, which covers the entire door opening.
Two-dimensional flow along an inclined plane wall and the impact of Coanda effect
on the flow character is described also in the paper of Allery et al.
According to Piper vice-president of engineering, John Becker, engineers are now experimenting using a Coanda effect
device that would channel the jet's exhaust in an appropriate direction to reduce nose-down moment created by adding power and nose-up trim changes when decreasing power.
Spray Aiming in Bombardier Beetles: Jet deflection by the Coanda Effect
The luminaire has also been tested to confirm that the suspended element will not interfere with the air-conditioning flow and, therefore, avoids the Coanda effect
Vlachopoulos has demonstrated the source and understanding of V-shapes in injection molded parts, has developed mathematical models of the polymer sintering process occurring in rotational molding, and has recently developed an analysis of the role of the Coanda effect
on the aerodynamics of blown film cooling as practiced in a large segment of the blown film ind ustry.
The jet, once formed, can be controlled by the Coanda effect
using an obstacle in the flow that is designed to optimize the performance of the meter.
The model will be used to predict the capacity of Coanda effect
screens and hence to choose appropriate screen sizes to achieve desired flow conditions.
