Sensitivity analysis of a heat transfer model for a cold-beverage cup system

Resumo

The temperature sensitivity of many goods is essential for enhancing the quality and consumer experience in several industries, particularly in beverages. From the brewing of teas and the fermentation of wines to the preservation of freshness in fruit juices, maintaining the optimal temperature is critical, therefore, any beverage container should maintain its temperature as long as possible. Mathematical modeling helps to achieve this by providing an overview of the heat transfer occurring within the beverage and its container. Afterward, the model should be assessed to determine the adjustment of the parameters to improve the thermal performance of the container. Sensitivity analysis is a fundamental tool for understanding any model’s behavior, structure, and response to changes in the input parameters. It can assess the impact of each input and its combinations on the variability observed in the model’s output. This work aims to assess the parameters of a cold-beverage cup model to minimize heat gain using sensitivity analysis.
