Energy and exergy and economic (3E) analysis of a two-stage organic Rankine cycle for single flash geothermal power plant exhaust exergy recovery

Fan, Guangli; Gao, Yingjie; Ayed, Hamdi; Marzouki, Riadh; Aryanfar, Yashar; Jarad, Fahd; Guo, Peixi (2021-12)

A two-stage ORC (Organic Rankine Cycle) is being proposed for the recovery and utilization of low-grade heat from single flash geothermal power plant exhaust flue fluids. The working fluids for two-stage the recovery system ...
Experimental investigation on the thermo-hydraulic performance of air–water two-phase flow inside a horizontal circumferentially corrugated tube

Ayed, Hamdi; Arsalanloo, Akbar; Khorasani, Saleh; Youshanlouei, Mohammad Mehdizadeh; Jafarmadar, Samad; Abbasalizadeh, Majid; Jarad, Fahd; Mahariq, Ibrahim (2022-09)

In this study, flow visualization, pressure drop and thermal characteristics of the corrugated tube with non-boiling air–water two-phase flow were experimentally studied. Glass tubes were used to visualize the flow patterns ...
Heat transfer improvement between a pair of heater and cooler inside an energy storage by using nano-encapsulated phase change material/water: A numerical modeling

Cao, Yan; Farouk, Naeim; Ayed, Hamdi; Aly, Ayman A.; Jarad, Fahd; Dahari, Mahidzal; Wae-hayee, Makatar; Saleh, B. (2022-02)

In the present study, the natural convection flow of water with Nano-encapsulated phase change material (NPCM) was simulated inside an insulated chamber, which a pair of pipes were considered as a heater and cooler sources ...
Inducing swirl flow inside the pipes of flat-plate solar collector by using multiple nozzles for enhancing thermal performance

Cao, Yan; Ayed, Hamdi; Hashemian, Mehran; Issakhov, Alibek; Jarad, Fahd; Wae-hayee, Makatar (2021-12)

In this numerical study, an attempt has been made to improve the thermal performance of the flat-plate solar collector (FPSC) by inducing the swirl flow inside the tube by the considered nozzles. To this end, the effect ...
MHD natural convection nanofluid flow in a heat exchanger: Effects of Brownian motion and thermophoresis for nanoparticles distribution

Cao, Yan; Ayed, Hamdi; Jarad, Fahd; Togun, Hussein; Alias, Hajar; Issakhov, Alibek; Dahari, Mahidzal; Wae-hayee, Makatar; El Ouni, M.H. (2021-12)

The free convection of Cu-water nanofluid is simulated and investigated inside a square heat exchanger chamber in the presence of MHD magnetic field. The Buongiorno model with the effects of Brownian and thermophoresis ...
Thermal, efficiency and power output evaluation of pyramid, hexagonal and conical forms as solar panel

Ayed, Hamdi; Moria, Hazim; Aldawi, Fayez; Farouk, Naeim; Sharma, Kamal; Youshanlouei, Mohammad Mehdizadeh; Mahariq, Ibrahim; Jarad, Fahd (2021-10)

Through the present investigation, the thermal and power output of novel-shaped solar panels are evaluated. For the cooling of the mentioned forms, forced air flow was utilized. Three novel shapes, of Pyramid, Hexagonal, ...
Thermal, hydraulic, exergitic and economic evaluation of a flat tube heat exchanger equipped with a plain and modified conical turbulator

Chen, Heng; Ayed, Hamdi; Marzouki, Riadh; Emami, Faezeh; Mahariq, Ibrahim; Jarad, Fahd (2021-12)

Increasing use of fossil fuels has led to serious consequences on the environment including global warming, pollution, and increased costs of heating systems. This indicates the importance of improving the efficiency of ...
