| 英文摘要 | This paper derives the upper bound on heat transport in supergravitational turbulent thermal convection analytically and numerically. Using a piecewise background profile, the functional inequality analysis delivers a suboptimal bound Nu less than or similar to-(3 root 3/2)(eta ln(eta)/(1-eta(2)))Ra-1/2 as Ra ->infinity, where Nu is the Nusselt number, eta is the radius ratio of the inner cylinder to the outer cylinder (0 |
