Аннотация

Probe sampling of gases is widely used in studies of high-temperature oxidation processes. This method directly provides information on the chemical composition of the reaction volume; however, the probe inevitably introduces thermal and gas-dynamic perturbations into the system. In this work, surface temperature profiles of a quartz probe in a premixed CH4/O2/Ar flame were measured at pressures of 1–5 atm. The measurements were made by a non-contact method using an IR camera, which was calibrated by thermocouple measurements taking into account flame shielding. The obtained data can be used as boundary conditions for numerical simulation of the sampling process, which will significantly improve the accuracy in error estimation when using probe sampling methods.
