Özet

This research, flow and thermal transport has experimentally investigated in flow channels with different fractal-like that branched sequentially. Here, flow analyzes under incompressible laminar (Newtonian and non-Newtonian) flow conditions in simple pipe and Y-shaped fractal- In the study carried out, fractal flow systems with one inlet, one outlet, one inlet, two outlets, one inlet, four outlets and one inlet, eight outlets were investigated. Likewise, these fractal type flow systems are produced in one, two, and three levels within themselves. In addition, these single inlet flow pipes are produced as single, two, four and eight outlets. The flow resistance and flow rates of fractal type flow systems produced in different types, as well as the pressure differences between the inlet and outlet of such flow systems, are extracted as an equation in this study.ike flow systems at different angles, diameters, lengths and levels are analyzed by simulations. The analyzes of these designed models were compared with the numerical results obtained in ANSYS. In the next stage, a new heat exchanger with fractal properties is designed, which increases the uniform surface temperature and reduces the pressure drop. It has been observed that such designed heat exchanger models show better thermal performance with less pump power. In successive branched Y-shaped fractal flow systems, the effects of secondary flows, velocity and pressure on regeneration of the boundary layer depending on angle at each branching level were investigated. As a result, it has been determined that fractal-like flow systems have lower pressure and better thermal performance.
