I began my academic career in 2013 as a teaching assistant and researcher in the Department of Mechanics at Sohag University. I received my master's degree from Sohag University in 2017. In 2022, I obtained my Ph.D. From Sohag University. In August 2022, I was promoted to Assistant Professor (Lecturer) at Sohag University.

The master's thesis focused on presenting alternative cooling technologies that can work with solar energy sources to solve the energy crisis facing the world, while the doctoral thesis focused on presenting an innovative technology to address the freshwater, energy, and climate change crises in an integrated and sustainable way. My research interests include environmentally friendly water desalination systems, refrigeration based on advanced solar technologies (adsorption systems), photovoltaic and thermoelectric power generation systems, energy storage and solar systems, heating, ventilation, air conditioning and refrigeration, heat pumps, non-steam compression cycles, and integrated refrigeration and desalination systems. My research work in the field of water desalination and energy is supported by the Science and Technology Development Fund (STDF) and the Academy of Scientific Research and Technology (ASRT). My experimental and numerical research has resulted in more than 17 papers in top-tier international journals, 8 under review, and 4 conference articles, reflecting excellence in research and publications. Also, I contributed to the establishment and obtaining international accreditation for a laboratory of refrigeration, air conditioning, and new/renewable energy applications in his faculty in measuring the energy efficiency of the refrigerator in May 2022 according to ISO/IEC 17025:2017 from Egyptian Accreditation Council (EGAC) and International Laboratory Accreditation Cooperation (ILAC).

Effect of improving thermal conductivity of the adsorbent on performance of adsorption cooling system
In this paper, effect of using metallic additives on thermal conductivity of granular activated carbon has been investigated. Fillings of iron, copper and aluminum at different mass concentrations ranging from 10 to 30% have been studied. The thermal conductivity of the combinations has been estimated experimentally. The thermal conductivity has been increased with the increase in metal concentrations. A mathematical ... Read more

Adsorption isotherms and kinetics of activated carbon/Difluoroethane adsorption pair: Theory and experiments
This study introduces a new adsorbent/refrigerant pair to be used in adsorption cooling applications. Adsorption isotherms and kinetics of Difluoroethane (HFC-152a) onto highly porous activated carbon Maxsorb III at temperatures ranging from 25 to 75°C have been investigated. Experimental data of adsorption uptake have been fitted with Dubinin–Astakhov (D–A) and Tóth equations. D–A equation is found to be more suitable ... Read more

Adsorption isotherms and kinetics of HFC-404A onto bituminous based granular activated carbon for storage and cooling applications
Adsorption characteristics of granular activated carbon/HFC-404A has been investigated in terms of adsorption isotherms and kinetics. AquaSorb 2000 which is bituminous based carbon has been used as an adsorbent. Experimentally and theoretical investigations have been conducted within temperature range of 25–75 °C. Experimental results have been fitted with Dubinin–Astakhov (D–A) and Tóth equations for the isotherms and linear driving force ... Read more

2018-11-21 20:46:13 | Keywords HFC410a- activated carbon, adsorption - cooling.,
This paper presents operation conditions and performance of an adsorption cooling system employing activated carbon powder (ACP)/HFC410a adsorption pair. The system has been modelled and simulated numerically and the effect of changing the operating conditions has been studied. The system is driven by a low grade heat source of temperature below 80ºC and effectively exploits solar heat and/or waste sources ... Read more
