PROPOSED MODEL One-dimensional, thermal resistance circuit representations of simple heat transfer arrangements are commonplace as a starting point in understanding the basic heat transfer attributes of a particular system. Indeed, as demonstrated by Bunker [17] and Town et al. [18], such circuits have found use in the simplified description of the heat flows in turbine cooling potential applications. current, whilst difference. In the thermal Consequently, temperature circuits, difference the ̇ is thermal analogous (ΔT) resistance provides to electrical circuit the analogy to Ohm’s law can be written as shown in equation 1. Based on Fourier’s law for conduction and the law of convective heat transfer, the resistance, R, can take the form of equation 2 or 3 respectively.
