Abstract: Drying is one of the main methods to extend the shelf life of fruits and vegetables. With the development of computer technology, computational fluid dynamics has been more and more widely used in the field of fruit and vegetable drying. This technique can simulate and predict the kinetic phenomena such as fluid flow and heat and mass transfer in the drying process of fruits and vegetables, and output the visualization results. Compared with traditional experiments, computational fluid dynamics technology has the advantages of energy saving, low cost, fast simulation speed and high flexibility. The working principle of computational fluid dynamics in the field of fruit and vegetable drying was introduced in detail in this paper, and the progress of it’s research in different fruit and vegetable drying methods was reviewed. This was followed by reporting the progress of the numerical modeling research of coupled shrinkage, and finally, the development direction of computational fluid dynamics in the field of fruit and vegetable drying was prospected in order to provide new insights and references for researchers.
