The current paper reports the measurement of laminar burning velocities of ethane air at atmospheric pressure and higher mixture temperatures using planar flames stabilized in an externally heated mesoscale diverging channel. The experiments were carried out at various equivalence ratios (? = 0.7 1.3) and mixture temperatures (350 600 K). The burning velocities and temperature exponents were determined using the planar flames stabilized at different channel locations due to varying mixture inlet velocities and temperatures. The measured burning velocities of ethane air flames at ambient conditions compare well with the Aramco mech 1.3 mechanism predictions. The burning velocities increase for high mixture temperatures, which can be attributed to the higher enthalpy of the mixture at these temperatures.
