The College of Engineering and Engineering Technologies holds the third clean energy forum

This study unveils a specialised swirl flow generator called the twisted hyperbolic turbulator for implementation in heat exchangers. The design of this geometry aims to induce bidirectional swirling flow. The water fluid flows through a heated tube at Reynolds numbers ranging from 2316 to 5096. This study examined the thermal-frictional effects of the new turbulator at various twisting angles ranging from 60 to 360°. The results indicated that as the twist angle rises, heat transfer also increases because of the fluid s intensified swirling and radial motion. Under ideal circumstances, a twist angle of 360° results in a notable increase in heat transfer by 256 % and a pressure drop by 625 %, accompanied by a TEF of 1.84. Longitudinal perforations were added to the selected turbulator at varying dimensionless distances (R = h/r) from the center, ranging from 9 to 3.6, with dimensionless hole diameters (P = h/d) ranging from 9 to 4.5. The results indicated that as the hole distance from the center of the tube increased, the TEF decreased while increasing the diameter of the perforations led to an improvement in TEF. The optimal configuration was found to be at P = 4.5, located at R = 6, resulting in a TEF of 2.02. https://www.sciencedirect.com/science/article/pii/ S2214157X24016976

Numerical investigation on thermal-fractional characteristics inside a heated tube enhanced with a novel grooved cone turbulator Abstract:

This study introduces a novel grooved cone turbulator (GCT) designed to enhance the thermal efficiency of a heated tube. The performance of the GCT-equipped tube was compared to that of a simple cone turbulator (SCT) and a plain tube. To investigate the impact of the GCT's geometric characteristics on hydrothermal parameters, tests were conducted on varying groove diameters (2.5- 10 mm), twist angles (0-270°), and pitch lengths (40-70 mm). The results demonstrate that heat transfer is directly correlated with both groove diameter and twist angle, while it is inversely correlated with pitch length. Notably, the use of the GCT increased the Nusselt number and friction factor by as much as 762% compared to the plain tube and by 221 % compared to the SCT- equipped tube. Among the three configurations tested-plain tube, SCT-equipped tube, and GCT-equipped tube-the GCT achieved the highest thermal enhancement factor (TEF) of 3.42. This optimal TEF of 3.42 was attained with a GCT featuring a twist angle of 90°, a groove diameter of 10 mm, and a pitch length of 5 cm.

Exergoeconomic investigation of a multi-generation system based on gas turbine, carbon dioxide recondensation, multi effect desalination and methanol-steam reforming

In the current research, the gas turbine unit has been used as a driver in the multi- generation system; due to the large amount of waste heat from the gas turbine, the carbon dioxide recondensation cycle has been used to recover it and produce power. Besides the output heat of the gas turbine's combustion chamber component is used in the methanol-steam reforming cycle to produce hydrogen. Finally, the desalination unit and the absorption chiller cycle by recovering waste heat in the last step, produces freshwater and cooling. Dissected from energy, exergy, exergo-economic, environmental and exego- environmental aspects, in this research. The thermodynamic analysis of each system component showed that the multi-generation systems could produce 1608 kW of electric power, 3.582 kg/s of fresh water, 0.1952 kg/s of hydrogen and 416.5 kW of cooling. Also, the energy and exergy efficiencies of the simultaneous production system were calculated as 53.35% and 66.56%, respectively. In the end, the CO2 emission rate and the sum unit cost of product were calculated as 205.1 kg/MWh and 233.2 $/kWh, respectively. https://www.sciencedirect.com/science/article/abs/pii/ S2451904924007881

Technical, economic, and environmental study with ANN-based optimization of a biomass-powered versatile/sustainable polygeneration system with carbon capture/utilization approach

This study delineates the development and evaluation of a power generation cycle characterized by the absence of carbon dioxide emissions, achieved through the direct combustion of oxygen and natural gas, a system commonly known as the Graz cycle. The analysis incorporates both thermodynamic and economic dimensions. In this system, hydrogen (H2) was initially produced from two separate sources to enable the conversion of carbon dioxide (CO2), sourced from the Graz cycle, into methane. The predominant method for hydrogen production is through the biomass gasification system, complemented by the use of hydrogen separation membranes. The solid oxide electrolyzer cell serves as the secondary source, wherein the necessary electrical energy is supplied by photovoltaic collectors. This research employs a robust methodological framework to undertake a comprehensive analysis of economic variables, with the objective of providing an accurate depiction of empirical conditions in the real world. This study conducts a comprehensive analysis of all relevant costs within the specified framework. A series of ANN-centered optimization analyses was performed to ascertain conditions that concurrently optimize the economic and thermodynamic dimensions of the system.
