Abstract
The coaxial thermocouple (CT) is the appropriate candidate to measure exceptionally transient condition due to having a fast-response behavior. The rate of response is varied from microsecond to millisecond. In this investigation, the K-type CT has been standardized under sudden step heating load for a short period of the experiment. The step heating load of 25 kW/m2 has been applied on the junction of the coaxial thermocouple and transient temperature history was recorded. The finite element investigation were also carried out to authenticate the experimental consequences. The surface heat flux has been assessed from transient temperature history recorded from the experimental and numerical outcome as well as compared with the input applied and the results obtained are within the accuracy of ±3.4%.
