Heat transfer is the core issue in many industrial applications where the production line works continuously. The additive manufacturing and automation systems introduced by the Internet of Things as an industry 4.0, heat exchangers, and heat transfer are becoming prominent areas. Hence, this paper focuses on the design and simulation of different shapes of fins for optimum heat transfer. The wind tunnel test is carried out to analyze the designed fin shape. The proposed research design is a nano-fin structure that can be applied to colossal equipment where velocity and pressure elements are considered. Also, the paper presents the nano-droplet handling solution for wind tunnel tests.
