Measurement Enhancement on Two-Dimensional Temperature Distribution of Methane-Air Premixed Flame Using SMART Algorithm in CT-TDLAS

Blog Article

In this study, the temperature distribution of the Methane-Air premixed flame was measured.In order vx bonnet protector to enhance the measurement accuracy of the CT-TDLAS (Computed tomography-tunable diode laser absorption spectroscopy), the SMART (simultaneous multiplicative algebraic reconstruction technique) algorithm has been adopted.Further, the SLOS (summation of line of sight) and the CSLOS (corrective summation of line of sight) methods have been adopted to increase measurement accuracies.It has been verified that the relative error for the temperatures measured by the thermocouples and calculated essie well nested energy by the CT-TDLAS was about 10%.
