In this contribution we have briefly introduced the problem of turbulent
thermal convection with a particular look at its transition to the ultimate
regime and the resolution requirements needed for the direct numerical
simulation of this flow.Comment: 10 pages, 6 figure

Toward DNS of the Ultimate Regime of Rayleigh–Bénard Convection

Heat transfer mediated by a fluid is omnipresent in nature as well as in technical applications and it is always among the fundamental mechanisms of the phenomena. The performance of modern computer processors has reached a plateau owing to the inadequacy of the fluid-based cooling systems to get rid of the heat flux which increases with the operating frequency [1]. On much larger spatial scales, circulations in the atmosphere and oceans are driven by temperature differences whose strength is key for the evolution of the weather and the stability of regional and global climate [2]
