The forced convection heat transfer behavior of water-titanium oxide (TiO₂) nanofluid was investigated numerically in a system consisting of a hollow tube in the middle of which water flows within a star-section channel. In this study, the motion and heat transfer of the nanofluid were modeled under the assumption of single-phase flow and the channel walls were evaluated under the condition of...

The thermal conductivity of nanofluids, suspensions of nanoparticles in base fluids, can be significantly influenced by the fractal nature of nanoparticle aggregates. Fractal structures, characterized by self-similarity across multiple scales, determine how nanoparticles cluster and form conductive pathways within the fluid. This study investigates the effect of fractal phenomena on the...

In recent years, there has been a growing emphasis on the use of sustainable energy resources to reduce carbon emissions and improve energy efficiency. In this study, an energy and exergy analysis of a trigeneration system consisting of a double-flash geothermal cycle, a domestic water heater (DWH) system, and a humidification- dehumidification (HDH) desalination unit has been investigated....

Dynamic Light Scattering (DLS), also known as photon correlation spectroscopy or quasi-elastic light scattering, is a widely used technique for characterizing nanoparticle size, size distribution, and aggregation behavior in dispersions, making it essential for nanofluid research engineered colloidal suspensions of nanoparticles in base fluids such as water, ethylene glycol, or oils. The...

In drilling operations, drilling fluids are used to improve drilling operations and bring drilling cuttings to the surface. The formulation of these fluids, commonly known as drilling mud, is one of the most important factors of a successful drilling operation. Considering that the major part of the costs of drilling a well is related to the supply and pumping of drilling mud, the use of more...
