Modelling of Ambient Factors and Quality Changes for Peach Cold Storage

Abstract

Spatial variation of temperature and relative humidity were estimated with Computational Fluid Dynamics (CFD) at top, middle and base levels for peach storage and verified with measured data in an experimental cold store having a chiller unit. Cooling system set up at +1 degrees C and 90% relative humidity. Ansys Fluent Software was used for CFD modelling. CFD models were validated by using differences of model estimations and measurements and evaluated by using descriptive statistics and variance analysis. Mean differences between the model and measured temperature and relative humidity were calculated as 1.02 degrees C and 11.66%, respectively. Fruit firmness, total soluble solid, titratable acidity, pH, respiration rate, external appearance and flavour analyses were determined.
