Surface Temperatures Determination with Influencing Convective and Radiative Thermal Resistance Parameters of Combustor of Gas Turbine ()
ABSTRACT
Surface
temperatures were determined with due consideration of the influencing thermal conditions of conductive, convective and radiative heat. A general condition of heat
influx to a point was formulated with the end effect of such influx to the
receiving point. It was noted that the heat flow will cause a rate of change of
internal energy of the point. Based on the theory of the rate of change of
internal energy, a combustor model of cylindrical cross-section was used to
generate out the timely temperature equation. Further work was done on this
model equation to convert it to non-dimensional. The conversion of this
equation was very essential in summing up the parameters that can influence the
timely generation of the temperatures. Interestingly, it is noted that when a
material withstands temperatures, it will equally withstand the thermal
stresses that inherently will be developed in it. From the results, the work
came up with a table showing the range of these slope figures of equations, a
point was also found for a vital recommendation for further studies, where such
figures can be used to check the suitability for thermal stress levels and the
lifetime of combustor of such thickness.
