Following on from Kuhn et al (2009) we study the capability of large eddy simulation with conjugate gradient heat transfer to predict thermal fluctuations with thermal mixing. Wall functions are used to model the wall heat transfer. The results show that the temperature variance on the outer skin of the solid is well predicted by the simulation. It is shown that the variance of thermal flux in the fluid closely maps the variance of thermal flux at the outer boundary of the solid. It is demonstrated that this occurs because the dissipation of temperature variance in the fluid controls the diffusion of temperature variance in the solid. Implications with respect to RANS modeling are discussed.
