Özet
Several research initiatives will investigate the application of nanofluids more fully in
order to enhance its commercialisation. Over the past ten years, the usage of magnetic
nanofluids for enhancing heat transfer has gradually grown as a result of its superior
thermal conductivity compared to other nanofluids. Nanoparticles have a significant
impact on the thermal properties of base fluids, such as thermal conductivity and viscosity.
When nanofluids are used, the double-tube heat exchanger's ability to transmit heat is
considerably enhanced. Other experiments showed that when the concentration of
nanofluids was reduced, the heat transfer coefficient increased even more. As a result,
more investigation was needed before using nanofluids in plate heat exchangers. The
colloidal suspension's thermal properties essentially differ from those of the base fluid. In
multi-component systems like colloidal suspensions, suspended particles interact with one
another significantly. The major goals of the current work are to assess the improvement in
heat transfer achieved by utilizing twisted tape and ferro-nanofluid, and to model the
impact of a magnetic field on ferro-nanofluid on the rate of heat transfer. Studies in
computational fluid dynamics (CFD) are conducted to have a deeper understanding of the
field of the stream. The (k-ε) model is used to explain the effects of the disturbance model,
which comprises the configuration of two vehicle conditions. Therefore, these Cartesian
direction frameworks will be addressed by the mathematical arrangement's procedures (x,
y, and z). Calculation with three layers is produced. The framework math will be created and networked using ANSYS software, after which one case will be replicated. The
mathematical results for the process of improving heat transfer utilizing twisted tape and
ferro-nanofluid with the effects of several conditions: rotational cycle, magnetic field
intensity, and concentration of ferro-nanofluid when using ferro-nanofluid with a magnetic
field to improve heat transfer, the influence of the aforementioned conditions on pressure,
temperature, and fluid velocity is also evident. The findings demonstrate that for all
operating circumstances, fluid pressure decreases while velocity increases and temperature
rises uniformly.
