In addition, the size of the tower is wanted to be optimized as much as possible, resulting in a smaller operational space with no yaw mechanism and less vibration. The ideal maximum efficiency, called the Betz limit, of the turbine is 59.4%. Here, a designed turbine is simulated to approach the limit. The airfoil blade profile NACA 5312 is selected, and a fixed flap at 80% of the chord length is introduced. The simulation result has been found to have an incremental value for the respective coefficient. The coefficient of lift Cl value has been doubled by the flap inclusion technique, resulting in a 35% reduction in the coefficient of drag Cd. The simulation of the blade coefficient of lift and drag is done by ANSYS Fluent, and the turbine simulation is done by Qblade DMST. The optimum design parameters are extracted and interpreted in different low wind speed conditions.

Adding time, as the fourth dimension, this technology ushered the potential of a massive evolution in fields of biomedical technologies, space applications, deployable structures, manufacturing industries, and so forth. This technology performs ingenious design, using smart materials to create advanced forms of the 3-D printed specimen. Improvements in Computer-aided design, additive manufacturing process, and material science engineering have ultimately favored the growth of 4-D printing innovation and revealed an effective method to gather complex 3-D structures. Contrast to all these developments, novel material is still a challenging sector. However, this short review illustrates the basic of 4D printing, summarizes the stimuli responsive materials properties, which have prominent role in the field of 4D technology. In addition, the practical applications are depicted and the potential prospect of this technology is put forward.
