Airflow Behavior Under Different Loading Schemes and Its Correspondence to Temperature in Perishables Transported in Refrigerated Containers
Supply chains are a highly evolving line of trading. The cool chains responsible for transportation of perishables are one subcategory that is demanding technological support to reduce the quality-related losses that they suffer due to temperature variations, among other reasons. Even distribution and ventilation of refrigerated air inside containers is imperative to maintain the perishables at the desired temperature range, avoiding degradation and spoilage. However, lack of research on airflow movement behavior—and convenient means of measuring spatial airflow speed—within packed containers makes it difficult to determine the hotspot scenarios, which is a prime cause of the said degradation. This paper presents a methodology to parametrically measure spatial airflow and analyzes the airflow behavior under different container loading schemes and how the airflow affects the internal pallet temperature.
