A Study on the Heat Transfer Characteristics According to the Impinging Distance of Stagnation Point in Syngas Impinging Jet Flames

An experimental study has been conducted to investigate the heat transfer characteristics of syngas/air mixture impinging jet flame with 10% hydrogen content. Effects of impinging distance, Reynolds number as major parameters on surface temperature of stagnation point were examined experimentally by the data acquisitions from k-type thermocouple. There were 2 times of maximum peak point of stagnation point with respect to the impinging distance for the investigation. As reynolds number increases, the nusselt number and convective heat transfer coefficient increased accordingly.
