Heat pipe performance and characteristic prediction model using one-dimensional analysis technique

This paper presents a 1-D modeling approach for conventional heat pipes, incorporating various variables and validated against experimental results. The model utilizes AMESim software to simulate thermal resistance and two-phase flow inside the heat pipe. By employing this efficient modeling technique, the study comprehensively explores the behavior of heat pipes under different operating conditions. The validated model serves as a valuable tool for predicting thermal performance and optimizing heat pipe design. The paper discusses the methodology, including the formulation of thermal resistance and two-phase flow models, and describes the experimental setup used for validation. Results show good agreement between simulations and experiments, indicating the accuracy of the model. The study emphasizes the practicality and time efficiency of 1-D modeling for evaluating different design configurations and parameters in heat pipe systems.
