Enhancing Heat Transfer in Heating of PET Bottles for Carbonated Beverages

This study investigates the enhancement of Heat Transfer (HT) during the heating process of PET-used PET (Polyethylene Terephthalate) bottles used for carbonated beverages, aiming to improve the efficiency and consistency of temperature distribution. This research provides a theoretical analysis to decide how the arrangement of bottles affects the quantity of energy stored in a solar heating system. The Thermal Energy Storage (TES) performance of commonly used PET bottles, ranging in size from 0.25,0.33,0.4,0.5,0.6,0.75,1.25, 2,2.25 x 10-3m3 and filled with chilled beverages at 280 kelvin and capped, has been examined while passing through warming Tunnel and hot air passed over the PET bottles with different velocities. The overall capacity of the energy transferred is inline arranged 924-2079,648-1499,358-819 x 10-3m3 with bottle Gap 0.25d,0.5d,1d respectively, and Staggered 892-1935,621-1377,338-729 x 10-3m3 with bottle Gap 0.25d,0.5d,1d respectively, A theoretical study has been conducted on the impact of intake velocity, intake temperature, bottle capacity, along with bottle layout on the quantity of energy. This study is particularly valuable for enhancing HT during the heating of PET bottles for carbonated beverages, as it offers insights into optimizing bottle arrangements and airflow conditions to improve thermal efficiency. By optimizing these factors, the heating process can be made faster and more energy-efficient, ensuring better quality and consistency in beverage production. Upon concluding this research, it has been shown that employing chilled beverage-filled PET bottles in the sensible thermal energy system is a practical, uncomplicated, and cost-effective method for transferring solar energy. Furthermore, due to the energy storage capabilities of PET bottles, there is no need for a heat exchanger during the charging operations. The working fluid, air, directly flows over PET bottles during the charging phases. It has been noted that reducing the diameter (volume) of the bottle resulted in an increase in the quantity of thermal energy.
