Nusselt number of a sphere in creeping flow
International Communications in Heat and Mass Transfer, 1990Abstract Rates of heat or mass transfer from a spherical droplet translating in a field under creeping flow conditions are examined. The existing expressions for Nusselt numbers are evaluated via an independent numerical analysis.

Nusselt number correlation for synthetic jets
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2015Among its many applications, synthetic jets have received much consideration as devices with the ability to enhance or even replace more conventional forced convection cooling techniques. This enhanced cooling is a result of the increase in turbulent mixing brought about by the oscillatory nature of the jet.

On the Monotonicity of the Nusselt Number as a Function of the Peclet Number
SIAM Journal on Applied Mathematics, 1994Summary: The author considers an arbitrarily shaped body of finite extent that is kept at a constant temperature and immersed in an infinitely large fluid bath. If the temperature on the body is greater than the ambient temperature of the fluid, it is shown that the heat necessary to keep the body temperature fixed is a monotonically increasing ...

Rayleigh–Bénard convection: Improved bounds on the Nusselt number
Journal of Mathematical Physics, 2011We consider Rayleigh–Bénard convection as modelled by the Boussinesq equations in the infinite-Prandtl-number limit. We are interested in the scaling of the average upward heat transport, the Nusselt number Nu, in terms of the non-dimensionalized temperature forcing, the Rayleigh number Ra.

Procedure for Optimal Formalization of Nusselt Number
2016Theoretical equations of Nusselt number are derived out based on our innovative similarity transformation model. Such theoretical equations show that the wall similarity temperature gradient is the only one unknown variable dominating the evaluation of the Nusselt number.

Physical model of the dependence of the Nusselt number on the Rayleigh number
Technical Physics, 2016The dependence of the Nusselt number on the Rayleigh number at the stage preceding the turbulent regime of convection is substantiated and obtained in analytic form. At this stage, the Nusselt number can be described by the power dependence on the Rayleigh number, which contains five constants.

Nusselt Number Measurements for Turbulent Rayleigh-Bénard Convection
Physical Review Letters, 2003We present high-precision measurements of the Nusselt number N as a function of the Rayleigh number R for a cylindrical sample of water (Prandtl number sigma=4.4) of height L approximately equal to 50 cm and aspect ratio Gamma identical with D/L approximately equal to 1 (D is the diameter) for 3 x 10(9)< or =R< or =6 x 10(10).

It can be argued that the exchange of energy between a solid and a fluid is important in most, if not virtually all, practical situations for which heat transfer plays a role. The goal of this chapter is to determine the convective heat transfer coefficients between the coffee and the mug and between the mug and ambient that have been used in the ...
