Abstract
We first introduce the local Bolgiano length, which depends on the vertical coordinate as a result of the inhomogeneity of the system. Based on the local Bolgiano length evaluated in numerical calculations, K41-OC scaling is expected in the central region and BO scaling is expected to exist only near the top and bottom plates. Then we discuss the experimentally observed scaling behavior in the central region, which has been reviewed in [1]. Next, we discuss the more recent analysis of the conditional temperature structure functions using experimental measurements at the bottom plate. We show that the experimental results are consistent with the theoretical expectations.
