Empirical and CFD analysis of silica nanofluid using a double pipe heat exchanger

摘要: The heat exchangers are widely used in the industrial processes to either or cool working fluids. They prevent utilization of an external source, which highly reduces cost production. Heat having high thermal conductivity required meet expanding needs. This study targets enhancement energy transfer by usage nanofluid instead conventional fluid such as water, concentric tube exchanger. was prepared silica nanoparticles, distilled water primary fluid. nanoparticles synthesized green synthesis method conformed X-ray Diffraction, zeta potential, FESEM techniques. hot liquid exchanger remains unchanged while, is replaced cold In this research, a double pipe modeled and meshed using ANSYS Fluent 14.5. transmission attributes equipment analyzed with help fluent software. amount for entire experiment about 5 l order get 0.05% volume concentration approximately 7 g were used. results Computational Fluid Dynamic (CFD) analysis experimentation compared justified. CFD outlet temperatures 313.18 354.03 K respectively, while experimental 322 346 K respectively. An improvement 10 °C found cooling upon nanofluid. outcome present research work, reveals that addition host leads significant properties.
