Summary on Grant Application Form
The first phase of the project will study moisture movement and temperature histories in a heated biomaterial and will include comparison with experimental results. This will involve extending the software to allow for mode stirring and sub-gridding. It will also involve moving from the Phoenics CFD software to the Physica software developed and maintained at Greenwich. The results will be compared with experimental work at Campden and Chorleywood Food Research Association and the mathematical model of moisture and temperature in microwaving, derived at the Bath Study Group in 1997; this model will be extended to a more general setting. The aim of this first phase is to demonstrate that computer modelling of the fully coupled problem provides the correct moisture movement trends for porous biomaterials and predicts their effect on the heating process.The second phase of the project will use the capabilities of the CFD software packages to study the detailed heating mechanisms involved in processing foods from a frozen state. The electromagnetic solver will be developed to model the effect of active packaging (susceptors and shields) as a part of this phase of the project. Detailed material properties and geometries for relevant (non-commercial) products will be set up in collaboration with Unilever. Unilever will also have a key role in evaluating computational results.
