Title: System and method of exhaust gas recirculation

Abstract

A system includes an exhaust gas an exhaust gas recirculation (EGR) mixer which includes a housing and a first passage in the housing. The first passage may be configured to supply an EGR flow into the housing. The system further includes a second passage in the housing, such that the second passage is disposed about the first passage. The second passage is configured to supply at least one fluid flow into the housing. The system also includes a region downstream from the first and second passages, and a fluid outlet downstream from the region.
