For many applications in different areas the convection heat transfer coefficient must be determined
for different proposes. Due to this, the variety of cases is big, such as next is exposing.
The external heat transfer coefficient in steam processing was determined experimentally in a pilot
scale. Using the finite element method, heat transfer equations were established and solved. The
actual retort temperature profile were used as boundary conditions. To analyse the time-variability
along a retort cycle, the heat transfer coefficient values were determined for various instants [1].
In foods and liquids like beverages, the cooling and freezing times are required. For this purpose,
the design of food refrigeration equipment are necessary. Also, refrigeration loads are required.
Using the surface heat transfer coefficient for the freezing or cooling operation the refrigeration
loads can be estimated. For this purpose, heat transfer coefficients from cooling curves were
obtained by means of a iterative algorithm. For various food items heat transfer coefficients were
determined [2].
