Description
Summary:Analyzing thermal liquid-based cooling systems is crucial for improving performance in fields such as fuel cells, energy storage, and spacecraft. For this purpose, we are going to simplify the 1D archetype model, considering Kapitza resistance, which aids rapid cooling system prototyping. To simplify the understanding of engine cooling physics, the regenerative coolant is used as an efficient liquid coolant. We have found that the fluctuations in the Nusselt number are crucial for precise thermal predictions using the continuum model. Moreover, the temperature and the coolant’s exit temperature are notably influenced by the channel’s geometry, and there exists an inverse relationship with the Nusselt number. Furthermore, considering temperature jump and Kapitza length, which relates to surface roughness, is essential, especially at the nanoscale. These factors are crucial for the precise modeling of cooling systems, and our parametric research template, grounded in the continuum model, provides valuable insights to enhance modeling.
