Considering that there is much to be explored regarding the Coanda effect, I decided to test the effects for myself in order to gain a better understanding of its in's and out's. I have seen through YouTube demos the advanced applications of the Coanda effect; to create hovercraft, to design non motorized aircraft rotors, etc. What I attempted to do in the following videos and illustrations is demonstrate how the Coanda effect is manipulated through volume.

The Coanda effect can not be properly demonstrated in this case as a result of the lack volume needed for a liquid to pour to the form of its container.

These examples prove my hypothesis that the Coanda effect is manipulated by volume of a fluid. In this case, volume affects viscocity. Vicosity, the stickiness or thickness of a fluid, has significent impact on the demonstration of the effect.

Coanda Effect

Week0 Activities

Write problem/project Goal

Use the Coanda effect in order to manipulate items to move.

My First Task

For this weekend, I am going to familiarize of the principles of the Bernoulli effect as well as the Coanda effect. When researching the Coanda effect, I will simulate it's two primary applications, with liquid and with air, and post my trials.

Week1 Activities

Summary of actual work over first weekend

In order to establish an understanding of the Coanda effect, I decided to test out the most popular techniques of demonstrating it; with water and with air. Through my research, I concluded that the Coanda effect is manipulated through three important aspects: speed, volume and design.

I personally tested the Coanda effect through air by taking a blow dryer and testing a uniquely designed paper as well as a carefully designed paper in order to demonstrate how the effect is manipulated by the design of an object, the volume (or viscosity) and the speed of the air. I also simulated a device through a unique design involving paper plates in order to simulate the effect; however, these attempts were not as successful as I hoped they would be. The purpose of my designs, and controlling the speed of the blow dryer were to affirm my aformentioned hypothesis regarding the Coanda effect.

Secondly, I tested the effect through liquid. I concluded that the Coanda effect can be demonstrated best with liquid if, and only if, a fluid fills a container at a large volume.

Week1 Narrative

Considering that there is much to be explored regarding the Coanda effect, I decided to test the effects for myself in order to gain a better understanding of its in's and out's. I have seen through YouTube demos the advanced applications of the Coanda effect; to create hovercraft, to design non motorized aircraft rotors, etc. What I attempted to do in the following videos and illustrations is demonstrate how the Coanda effect is manipulated through volume.

In this video, [[1]], it is demonstrated that a pitcher of water is filled to the top, and is being poured slowly into a sink. As the water is being poured out of the pitcher, it clings to the side of the pitcher and creates a stream that trickles aound the round form of the pitcher. But in this video,[[2]], the pitcher is not as full as demonstrated in the first video; it doent trickle down the form of the pitcher, rather, it pours right into the sink. The Coanda effect can not be properly demonstrated in this case as a result of the lack volume needed for a liquid to pour to the form of its container.

These examples prove my hypothesis that the Coanda effect is manipulated by volume of a fluid. In this case, volume affects viscocity. Vicosity, the stickiness or thickness of a fluid, has significent impact on the demonstration of the effect.
