IR Experimental investigation on twin synthetic impinging jets heat transfer behaviour

Abstract

In this work an

Experimental method to quantify the efficiency of the first two operational stages of nanosecond dielectric barrier discharge plasma actuators

“…The camera is located on a traverse system and the ns-DBD actuator is imaged through a parabolic mirror in order to increase image magnification. The IR acquisition system is calibrated using a black body built in-house [30] and the mirror is kept installed during the calibration process to take into account IR emission losses [31]. The viewing angle with respect to the model surface is kept smaller than 50 degrees such that the emissivity of Lexan® can be regarded as constant and independent of the viewing angle [29].…”
