Title

A Facility For High-Pressure Laminar Flame Speed Measurements

Abstract

A constant-pressure cylindrical flame speed vessel (30-cm ID, 36.2-cm length) has been built for the study of constant-pressure, freely propagating, spherical flames. A Z-type schlieren setup, using either a vertical or a circular knife edge, in combination with a high-speed camera is used to capture the progression of the flame. Flame speed data were analyzed using special image tracking software. A linear regression of flame speed versus stretch was obtained, giving the Markstein length and the unstretched flame speed. A high-speed, piezo-resistive pressure transducer is used to obtain pressure data during the experiment and guarantees constant-pressure conditions. The vessel was designed for initial pressures up to 30 atm, where full use of the 12.7-cm aperture can be utilized within 3.5% of the pressure rise. Due to its high thermal conductivity, the high-strength Al vessel will facilitate future heated applications. Several methane-air mixtures have been tested around 1 atm and show good agreement with published data.
