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-like. 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. Fractal-like 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.
