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.

Nusselt Number Correlations

2015
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 ...

Estimation of Nusselt number and effectiveness of double‐pipe heat exchanger with Al2O3–, CuO–, TiO2–, and ZnO–water based nanofluids

Heat Transfer, 2020
This paper deals with experimental studies carried out to analyze heat transfer characteristics of Al2O3–, CuO–, TiO2–, and ZnO–water based nanofluids in a double‐pipe, counter flow heat exchanger for different volume concentrations (0.025%, 0.05%, 0.075%

Physical model of the dependence of the Nusselt number on the Rayleigh number [PDF]

Technical Physics, 2016
The 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.

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 ...

Development of multilayer perceptron artificial neural network (MLP-ANN) and least square support vector machine (LSSVM) models to predict Nusselt number and pressure drop of TiO2/water nanofluid flows through non-straight pathways

Numerical Heat Transfer, Part A Applications, 2018
In this study, Multilayer Perceptron Artificial Neural Network (MLP-ANN) model and Least Square Support Vector Machine (LSSVM), were developed to predict the thermal performance and pressure loss of nanofluid flow through coils as non-straight pathways ...

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.
