Heat transfer intensification by jet impingement – numerical analysis using RANS approach [PDF]
E3S Web of Conferences, 2019 Jet impingement is a method of the heat transfer enhancement applied in the engineering systems. The idea is to generate fast-flow fluid jet which impinge on the heated (or cooled) surface, causing significantly higher heat transfer rate.

Scale-adaptive simulation of unsteady cavitation around a naca66 hydrofoil [PDF]
, 2019 Distances between consecutive aftershocks are analysed by means of mono- and multifractal theory with the aim of quantifying the complexity of the physical mechanism governing them, as well as their predictability and predictive instability.

DC-RAN dynamic coverage methods to improve its performance
Wasit Journal of Engineering Sciences, 2023 Abstract In cellular networks, there are usually times when the density of the network changes at different times of the day, where congested areas attract a large demand for communications and data, which generates peak demand at specific times of the day, and vice versa also happens in the same area but at another time of the day, and in order ...

A Deep Learning-Based Mapping Model for Three-Dimensional Propeller RANS and LES Flow Fields
Applied SciencesIn this work, we propose a deep learning-based model for mapping between the data of the flow field of the propeller generated by the Reynolds-averaged Navier–Stokes (RANS) and those generated by Large Eddy Simulation (LES).
