The oil and gas sector has recently shown an interest in hydrodynamic cavitation for enhancement, as it allows reducing transportation refinement costs. This work presents a fluid-dynamic study of Colombian at different temperatures passing through vortex reactor. First, experimental design was elaborated, establishing the temperature quantity injected hydrogen donor factors final viscosity res...

This paper presents a numerical study of waste heat recovery from fluid stream using thermoelectric devices. The system consisted square section duct with spherical porous media placed in its central region. Hot air circulates continuously through the and exchanges energy solid matrix subsequently modules. mathematical model was solved ANSYS/FLUENT software, requiring implementation user-define...

Sloshing has many industry applications, namely in offshore engineering, aerospace, ship building, and manufacturing. simulation is essential to better understand the sloshing pattern consequently improve tank design reduce noise levels, stresses on structure, optimize baffle configurations arrangements. Thus, aim of this study determine effects perforated (porous) imperforate (solid) baffles p...

The results of computational and experimental studies a model hypersonic convergent air intake are presented. Experimental were carried out in hot-shot wind tunnel IT-302M SB RAS at Mach number M = 5.7 an angle attack α 4 °. Numerical modeling was three-dimensional setting the ANSYS Fluent software package. calculations versions using different turbulence models: k- ɛ standard, RNG ɛ, ɷ standar...

La resistencia a la cavitación es un requerimiento importante en el diseño de turbinas hidrocinéticas para aplicaciones marinas o fluviales dado que se ha demostrado puede contribuir al desgaste, corrosión, vibración y fatiga los álabes turbina. presencia conducir disminución del rendimiento turbina reducción su vida útil. Por lo tanto, fundamental incluir estudio análisis desarrollo sistemas h...

Excessively high temperatures will interfere with the operation of components and damage equipment. The key to fixing this is generate uniform heat dissipation maximize dissipation. This paper proposed a cold plate three S-type multistage Tesla valves (ST-MSTV). Thermal performance was first evaluated flow direction angle. effects channel valve spacing on were then investigated Ansys Fluent sof...

Different techniques have been used to achieve a high heat transfer rate. Among them, one of the advanced is suspension nanoparticles in base fluids as water and coated with aluminum titanium. The present work has carried out on double pipe exchanger twisted tape insert twist ratio (y/w = 4 6) thickness (0.8mm) for investigation nanofluid counter flow arrangement under turbulent conditions. com...
