EDUCATIONAL experiments with Coanda ejectors

Experimental EDUCATION for students

Before any design of the ejectors we have to understand how ejectors works. Ejectors extract or add flows in usual activities without any mechanical moving parts.

The design and manufacture of any Coanda ejector needs to be very accurate and precise and also having very low weight. Any Coanda ejector has 2 main dimensions and also 3 geometric dimensions and 2 other thermodynamic supply parameters (pressure and temperature) in order to control the flow and make the necessary adjustments for each flow conditions at any customers needs.

The Coanda ejector is more complex flow device than a simple rotor fan or blower therefore the flow characteristics is done by adjustments of geometric dimension, pressure and temperature. The input temperature is critical for the efficiency of the device.

Most of the time we have designed ejectors for a certain application. The design might be rectangular, circular, lens shape or other section shape.

To understand the limits of the design and useful work we may organize:

LEARNIG experiments

We have learned from Henri Coanda researches and experiments. It is an honor for us to share to the younger students these results. It is easy to learn when you see and interact with the phenomenon. Coanda ejectors are based on Coanda effect and interaction with a Coanda ejector will impact your life and airflow understanding. The learning models are designed to work with low velocities and are safe for students.

LIVE science shows

We have learned from Henri Coanda researches and experiments. It is an honor for us to share to the younger students these results. The science shows are includes spectacular exemplification of the Coanda effect and ejectors for aerospace, transportation and ventilation. The learning models are designed to work with low velocities, to be interactive, transparent in some zones and are safe for students.
