In this study, the flow, heat transfer, and thermal performance of a Lancet-type finned cross-flow heat exchanger with different geometrical plate arrangements are investigated numerically and experimentally. The heat transfer between hot fluid (air) and cold fluid (water) in the fins placed in the test region and the pressure drop in the test region are investigated at different Reynolds numbers (5000–22,000). Air (ρ≅1.274 kg/m3 and Pr = 0.711) and water (ρ = 997.4 kg/m3 and Pr = 6.78) are used as cold fluids. Taguchi experimental design method, Nusselt number, and friction factor are considered as performance parameters. As a result of the experiments performed on the designed Lancet-type finned cross-flow heat exchanger, flow and heat transfer analyses were carried out at different temperatures and flow rates. Similarly, the flow and heat transfer characteristics, three-dimensional Navier–Stokes equations, and energy equations of numerical fluid dynamics ANSYS-FLUENT air flow k-ε were obtained according to the standard model. After performing tests and using computers, it was found that the cross-flow heat exchanger works better when the plates are shifted than when they are lined up in a straight line.
