Why is it important?
This study investigates mass and heat transfer in a van der Waals liquid drop in microgravity with hot air atmosphere. Using Smoothed Particle Hydrodynamics (SPH) with an adaptive scheme, effects of the diffuse interface are considered via the Korteweg tensor. Spinodal decomposition sets initial conditions. Temperature profiles match in phases but differ at the interface. Damped oscillations precede mass transfer. The interface plays a crucial role in mass transfer initiation, influencing temperature and drop radius evolution. Temperature oscillations affect drop radius decay, deviating from linear trend at higher temperatures.
Perspectives
Advances in understanding mass and heat transfer under specific conditions: The study provides detailed insights into how mass and heat transfer occur in a liquid droplet surrounded by hot air in microgravity. These conditions are relevant for various industrial and scientific applications, such as materials manufacturing, medicine, food engineering, etc. Applications in space and microgravity technology: Research in microgravity is essential for the development of space technologies, and understanding mass and heat transfer processes in such environments is crucial for designing systems and experiments in space. Improvement of numerical simulation models: The use of Smoothed Particle Hydrodynamics (SPH) and the inclusion of an adaptive scheme represent an advancement in numerical modeling of these systems. This may have broader applications in other engineering fields and materials science. Relevance to process engineering and materials technology: Understanding mass and heat transfer processes in specific environments can lead to improvements in materials manufacturing and optimization of industrial processes.
