WebHowever, this compensated Nusselt number monotonically increases for Rayleigh number larger than 10 10. For the exponent of m = 1/3, the constant region of the compensated Nusselt number is at higher Rayleigh numbers between 10 10 and 10 14, as shown in Fig. 3 B. However, the trend at ultra-high Rayleigh number (> 10 14) is not clear WebDownload scientific diagram Relationship between Rayleigh number, Ra, Reynolds number, Re, and Prandtl number, P r, after Grossmann & Lohse (2002). from publication: The … sight 意味

WebWhat is Rayleigh number? Rayleigh number is defined as the product of grashof number and Prandtl number. The rayleigh number is denoted by the symbol Ra. As per the … Web1. Derivation of Nusselt number-Rayleigh number equation Recent experiments (Chu & Goldstein 1973; Garon & Goldstein Threl- fall 1976) have yielded excellent data on the … WebWhereas the low–Reynolds number regime was well explored in the 1980s and 1990s of the past century, in the fully turbulent regime major research activity developed only in the past decade. In this article, we review this recent progress in our understanding of fully developed Taylor-Couette turbulence from the experimental, numerical, and theoretical points of view. sight翻译
