Description

<p>A formation process of CO with effects of air dilution on turbulent flame under elevated pressure has been experimentally investigated. Flow velocity ratio of premixed gas and dilution air (Ud/U) was controlled. CO distribution in the burned gas, temperature of the combustion field and flow velocity distribution were measured by CO-TALIF method, gas analyzer, R-type thermocouple and hot wire probe respectively. Results indicated that the concentration of CO increases as Ud/U increased at any measurement point. The CO concentration has the maximum value in a certain burner height direction under each condition.</p>
