In studying transport phenomena in foods, the heat, mass, and momentum transfer occurring at the boundaries of a food offer intriguing problems for food engineers.
It is common to encounter these types of problems either at the stationary boundary at the surface of a food, or at moving boundaries within the food, i.e., the freezing front in a food during the freezing process. A fundamental understanding of the transport phenomena at the boundaries is often a prerequisite to developing computer-ai…
