TLDR
In this paper, the Navier-Stokes equations in axisymmetric cylindrical coordinates were used for predicting detailed flow patterns and temperature profiles during natural convection heating of canned liquids.Abstract:
Amathematical model was developed for the first time for predicting detailed flow patterns and temperature profiles during natural convection heating of canned liquids. Finite difference methods were used to solve the governing Navier-Stokes equations in axisymmetric cylindrical coordinates. A vorticity-stream function formulation of the equations was used. Details of the numerical techniques used are discussed. Plots of transient isotherms, streamlines and velocities are provided. From the standpoint of food processing, the slowest heating points migrated within the bottom 15% of the can with no particular pattern of migration.read more

Numerically Predicted Transient Temperature and Velocity Profiles During Natural Convection Heating of Canned Liquid Foods
TL;DR: In this paper, the authors presented numerical predictions of transient flow patterns and temperature profiles during natural convection heat transfer of a liquid in a uniformly heated cylindrical can and found that the fastest heating location in the fluid was a donut-shaped region close to the bottom of the can at about one-tenth the can height.
