Harnessing Wind Energy for a Green Hydrogen Revolution in Oman: Potential, Challenges, and Economic Viability

Navid Nasiri, Morteza Mohammadzaheri, Rayyan Muhammad Rafikh et al. · The Journal of Engineering Research · 2025 · 10.53540/1726-6742.1309

This study is the first to comprehensively evaluate green hydrogen production from wind energy across 14 geographically diverse sites in Oman, filling a critical research gap in the MENA region where wind-to-hydrogen feasibility remains underexplored. Unlike prior studies focused on Europe (Dincer & Acar, 2015) or sola …

MODELLING OF ELECTRICAL SUBMERSIBLE PUMPS FOR PETROLEUM MULTIPHASE FLUIDS, AN INTELLIGENT APPROACH SUPPORTED BY A CRITICAL REVIEW AND EXPERIMENTAL RESULTS

Morteza Mohammadzaheri, Reza Tafreshi, Zurwa Khan et al. · The Journal of Engineering Research · 2019 · 10.24200/tjer.vol16iss2pp77-86

This paper initially reviews existing empirical models which predict head or pressure increase of two-phase petroleum fluids in electrical submersible pumps (ESPs), then, proposes an alternative model, a fully connected cascade (FCC in short) artificial neural network to serve the same purpose. Empirical models of ESP …

Investigation of Effective Parameters of Drop-on-Demand Droplet Generator

Mojtaba Ghodsi, Yousef Hojjat, Hesam Sadeghian et al. · The Journal of Engineering Research · 2017 · 10.24200/tjer.vol14iss2pp182-190

This article presents a design and development of a drop-on-demand (DOD) droplets generator. This generator uses molten metal as a liquid and can be used in fabrication, prototyping and any kind of printing with solder droplets. This setup consists of a vibrator solenoid with tunable frequency to produce a semi-spheric …

An Enhanced Smith Predictor Based Control System Using Feedback-feedforward Structure for Time-delay Processes

Morteza Mohammadzaheri, Reza Tafreshi · The Journal of Engineering Research · 2017 · 10.24200/tjer.vol14iss2pp156-165

This paper presents enhanced Smith predictor based control systems (SPBCSs) for processes with a time-varying or fixed time delay. This work focuses on improving the arrangement and asynchrony of SPBCS components rather than the design of the predictor and the feedback controller, which have been well discussed in the …
