Actual temperature-time profiles of meat cube were measured at flow rates of 15, 30, and 45 L/min and viscosities from 0 to 15 cp, and mean values of convection heat transfer coefficients ranged from 792 to 21207 W / m2.K. Convection heat transfer coefficient increased with increase in ...
The dimensionless numbers used for forced convection heat transfer coefficients are the Nusselt number (Nu), Prandtl number (Pr), and Reynolds number (Re). Definitions of Nu, Pr, and Re are shown below. The heat transfer coefficient, h, appears in the Nusselt number, so the correlations ...
Many handbooks contain tabulated values of the convection heat transfer coefficients for different configurations. The following table shows some typical values for the convective heat transfer coefficient: Medium Heat Transfer Coefficient h (W/m2.K) Air (natural convection) 5-25 Air/superheated ...

Natural convection heat transfer is found in many industrial applications such as nuclear technologies, electronic circuit board cooling, solar panel cooling and many other fields. When natural convection heat transfer coefficients are insufficient, passive heat transfer enhancement devices (called ribs/fins...
