Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

This study presents a deep learning-based framework to recover high-resolution turbulent
velocity fields from extremely low-resolution data at various Reynolds numbers by utilizing …

The occurrence of turbulent pulsations in straight pipes of noncircular cross-section leads to
