Coanda effect

This was presented on May 2019, and I have a video of my presentation. The purpose of this presentation is to introduce the mathematical mechanisms that explains Coanda effect.

Introduction

What is Coanda effect?

Principles

What is the mechanism?

Modeling

Case 1: Plane surface

From 1960 research(Ref 1), the rettachment is the main purpose.

Case 2: Curved surface

From 2012 research(Ref 3), mathmatical modeling of curved surface coanda effect was conducted.

Case 2-extra: Also curved surface

From 1954 research(Ref 2), using complex analysis.

Verification

From 2004 research(Ref 4)
