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 ...

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.

A study of Nusselt and Sherwood numbers in a monolith reactor
Catalysis Today, 1999Abstract A two-dimensional model of a single channel of a monolith reactor is used to evaluate the values of the Nusselt and Sherwood numbers under reaction conditions. The circular channel is assumed to have axisymmetry with a first-order reaction occurring at the wall.

Drop Nusselt numbers in dropwise condensation
Applied Scientific Research, 1974Most of the theoretical studies in dropwise condensation have based their analysis on the principle that the heat transfer rate limiting mechanism in dropwise condensation is the conduction of heat through drops. Based on this principle, Fatica and Katz presented shape factor values for droplets and these values have been used by other studies.

Comparative Study of Nusselt Number Correlations for Hitec Molten Salt
2020 2nd Novel Intelligent and Leading Emerging Sciences Conference (NILES), 2020Molten salt has been realized as a potential candidate as a clean non-pollutant heat transfer fluid for concentrated solar power plants because of its high heat capacity and broad ranges of operational temperatures. In this study, the Nusselt number of the commercially known Hitec molten salt is numerically assessed, using k-e model turbulence model ...

Nusselt number for steady Poiseiulle flow through a pipe
Mechanics Research Communications, 1994Abstract The efficiency of the heat transfer mechanism for the fully developed steady Poiseiulle flow of a viscus incompressible fluid through a pipe of uniform but arbitrary cross section, when the wall of the pipe is maintained at a constant temperature, is measured by the average Nusselt number Nu .

Prandtl number dependence of Nusselt number in direct numerical simulations
Journal of Fluid Mechanics, 2000The dependence of the Nusselt number Nu on the Rayleigh Ra and Prandtl Pr number is determined for 104 < Ra < 107 and 0.07 < Pr < 7 using DNS with no-slip upper and lower boundaries and free-slip sidewalls in a 8 × 8 × 2 box. Nusselt numbers, velocity scales and boundary layer thicknesses are calculated.

Nusselt Numbers in Rectangular Ducts With Laminar Viscous Dissipation
Journal of Heat Transfer, 1999In this paper, the steady temperature distribution and the Nusselt numbers are analytically determined for a Newtonian incompressible fluid in a rectangular duct, in fully developed laminar flow with viscous dissipation, for any combination of heated and adiabatic sides of the duct, in H1 boundary condition, and neglecting the axial heat conduction in ...

A New Correlation of Nusselt Number for Impinging Jets
Heat Transfer Engineering, 2009Jet impingement heat transfer has received a remarkable amount of attention by researchers throughout the world for many years due to widespread interest from both academic and industrial points of view. However, the fluid dynamics involved with arrays of jets are very complex and still not completely understood. Therefore, a functional relationship of
