Abstract

A device is provided. The device includes an inlet manifold configured to direct an exhaust gas flow within the device, an air inlet configured to introduce an airflow within the device and at least one surface of the device having a Coanda profile configured to entrain incoming air through the exhaust gas flow to generate a high velocity airflow.

Claims

1. A device, comprising:

an inlet manifold configured to direct an exhaust gas flow within the device;

an air inlet configured to introduce an airflow within the device;

at least one surface of the device having a Coanda profile configured to entrain incoming air through the exhaust gas flow to generate a high velocity airflow;

wherein the Coanda profile comprises a logarithmic profile; and

wherein a ratio of the mass of air entrained by the device and mass of the exhaust gas flow is between about 5 to about 22.
