Abstract
The numerical analysis of the thermal Ice Protection System(IPS) is conducted by heat transfer analysis between an icing simulation and an internal heat transfer simulation. For accurate heat transfer analysis, the coupling method is required since heat transfer occurs in each region. A loose-coupling method, which is used by most of the prior research, does not take into account the effect of the internal heat transfer on the convection heat of external flow. While the tight-coupling method takes longer to calculate than the loose-coupling method, it can result in high accuracy. In this study, a convective heat transfer coefficient is obtained by the tight-coupling method in dry conditions without water film. A comparative analysis was then performed with experimental results and other numerical analysis studies. The tight-coupling method showed more excellent agreement with the experiments than the loose-coupling method. Furthermore, it is confirmed that the developed numerical method has a great performance.
