A regenerator—prediction of nusselt numbers

International Journal of Heat and Mass Transfer, 1969
Abstract The dynamics of a parallel plate regenerative heat exchanger are studied using a model in which resistance to heat transfer is due to diffusional resistance in the fluid in the direction transverse to flow. The resultant Nusselt number is a function of time as well as longitudinal distance from the entrance of the exchanger and is not a ...

A New Nusselt Number for Complicated Configurations

Volume 3: Gas Turbine Heat Transfer; Transport Phenomena in Materials Processing and Manufacturing; Heat Transfer in Electronic Equipment; Symposium in Honor of Professor Richard Goldstein; Symposium in Honor of Prof. Spalding; Symposium in Honor of Prof. Arthur E. Bergles, 2013
Convective heat transfer over surfaces is generally presented in the form of the heat-transfer coefficient (h) or its nondimensional form, the Nusselt number (Nu). Both require the specification of the free-stream temperature (Too) or the bulk (Tb) temperature, which are clearly defined only for simple configurations.

Nusselt number of a sphere in creeping flow

International Communications in Heat and Mass Transfer, 1990
Abstract 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.

On the Monotonicity of the Nusselt Number as a Function of the Peclet Number

SIAM Journal on Applied Mathematics, 1994
Summary: 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 ...

Nusselt number correlation for synthetic jets

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2015
Among 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.

Rayleigh–Bénard convection: Improved bounds on the Nusselt number

Journal of Mathematical Physics, 2011
We 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.
