Influence of Nusselt number on weight loss during chilling process
AbstractThe coupling of the heat and mass transfer occurs on foods during chilling process. The temperature of foods is reduced while weight changes with time. Chilling time and weight loss involve the operating cost and are affected by the design of refrigeration system.

Classical 1/3 Nusselt number scaling in highly turbulent compressible convection [PDF]
Planetary and stellar convection, which are compressible and turbulent, remain poorly understood. In this paper, we report numerical results on the scaling of Nusselt number ($\mathrm{Nu}$) and Reynolds number ($\mathrm{Re}$) for extreme convection.

Local Nusselt number evaluation in the case of jet impingement [PDF]
Jet impingement still is one of demanding cases regarding computational fluid dynamics, due to its highly turbulent behaviour, with occurrence of turbulent-laminar transition. Even recently developed methods exhibit some drawbacks - RANS based simulations lack accuracy, LES and DNS based ones require too much computational time.

Fronts in reactive convection: bounds, stability and instability [PDF]
We consider front propagation in a reactive Boussinesq system in an infinite vertical strip. We establish nonlinear stability of planar fronts for narrow domains when the Rayleigh number is not too large.

Relationship between Nusselt number and the thermoviscous (Rott) functions [PDF]
The characterization of the thermal properties of regenerator materials has traditionally been studied by measurement of the heat transport of a gas passing through a regenerator flanked by two heat exchangers. The results for heat transfer between the gas and regenerator are typically expressed as a nondimensional Nusselt number.
