Improving the quality of stored potatoes using computer modelling
Uniformity of air flow is a key factor affecting the quality of potatoes during storage. Stores with non-uniform air flows often suffer from condensation, consequent rotting and poor quality of the potatoes. A model, solved using computational fluid dynamics software (cfds-cfx4), was produced to identify modifications to air distribution systems that would improve the uniformity of the air flows. The model treats the potatoes as a porous resistance around the ducts and predicts the flows inside the air supply ducts. A commercial store which experienced condensation and rotting each year was modified on the basis of predictions from the model and both problems in the store were eliminated. The model is simple and cost effective enough to be used in commercial applications.
