Recent numerical work on two-dimensional Rayleigh-Benard convection has led to a new explanation for the exponential nature of probability density functions (PDF) for temperature fluctuations in a fixed point of the cell. The argument was based on the exponential shape of PDF for temperature fluctuations all over the cell, by taking into account the geometrical features of the system dynamics. In this paper we present the results of three-dimensional numerical simulations, which provide full support for the aforementioned explanation.

Abstract
Recent numerical work on two-dimensional Rayleigh-Benard convection has led to a new explanation for the exponential nature of probability density functions (PDF) for temperature fluctuations in a fixed point of the cell. The argument was based on the exponential shape of PDF for temperature fluctuations all over the cell, by taking into account the geometrical features of the system dynamics. In this paper we present the results of three-dimensional numerical simulations, which provide full support for the aforementioned explanation.File in questo prodotto:
