Heat Transfer, EarlyView.ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

MEAN NUSSELT NUMBER CORRELATION FOR TISE HEATSINK THERMAL DESIGN
Revista de Engenharia Térmica, 2020 This work was developed from a review of the technical literature for the thermal design of parallel plates heat sinks with uniform cross section cooled by airflow with the TISE (Top Inlet Side Exit) configuration. Due to an observed lack of agreement of the literature correlations among themselves and also with the available experimental results ...

Refinement of Nusselt numbers in drying processes
Mathematical Modeling and ComputingIt is proposed to refine the calculation of Nusselt numbers by considering the mass transfer coefficient in the evaporation zone, which is significantly larger than the molecular mass transfer coefficient of vapour. This refinement aims to address the discrepancy between the elevated Nusselt criteria observed during drying and the criteria determined ...

A Study on Preventing Thermal Runaway of Contaminated Ammonium Nitrate Prill in Bulk Storage
Propellants, Explosives, Pyrotechnics, EarlyView.Schematic illustration of a contaminated region of ammonium nitrate prill undergoing exothermic decomposition, producing gases containing NOx. The interstitial flow of these heated gases rapidly raises the temperature of ammonium nitrate along the flow path.

Moist convection and radiative cooling: Dynamical response and scaling
Quarterly Journal of the Royal Meteorological Society, EarlyView.The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

, 2005 We describe three apparatus, known as the large, medium, and small apparatus, used for high-precision measurements of the Nusselt number N as a function of the Rayleigh number R for cylindrical samples of fluid and present results illustrating the ...
