Numerical study of porosity effects on temperature and fluid flow in Black Sea gas hydrates

Numerical temperature and fluid flow simulations were conducted using ANSYS Fluent to investigate the influence of porosity variations on the temperature distribution within the gas hydrate layer. The study was carried out in the Black Sea region, where the gas hydrate deposits are of particular interest due to their potential for energy resources. The simulations explored various porosity levels within the hydrate layer to observe their effect on thermal behavior and fluid dynamics. The results revealed that porosity plays a significant role in modulating the temperature distribution within the gas hydrate layer, with lower porosity models exhibiting higher temperatures compared to higher porosity models. These findings are consistent with the understanding that lower porosity environments tend to have reduced heat dissipation capabilities, leading to localized temperature increases. This study provides valuable insights into the thermal dynamics of gas hydrate systems and highlights the importance of porosity as a key factor in determining the stability and distribution of gas hydrates in marine environments.
