The copper coil insert has been tested via experimental research which presented data sufficient enough to conclude that such turbulators would be effective when used in all high-heat load/flux components at the Advanced Photon Source at Argonne National Laboratory. The present investigation discusses the numerical simulation of the wire coil insert using spectral element analysis. The non-dimensionalized heat transfer coefficient, Nusselt Number, and eddy diffusivity are used to draw conclusions regarding main transport mechanisms and optimal design parameters of the wire. The optimal parameter case, as determined by Collins et al. is analyzed here. This analysis confirms the conclusion of previous experimental research, shows that the increase of heat transfer due to the turbulators is not highly correlated to material choice of the turbulator, and maintains that the main heat transfer mechanism is turbulent mixing.","abstract_html":"The enhancement of turbulance through the use of turbulators has been studied extensively in the past.
