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.
