Abstract

As cities grow, the demand for energy increases, necessitating a corresponding increase in energy supply. Since urban areas consume the majority of the world’s energy, switching to renewable energy sources is essential. Wind energy is one of the most popular renewable energy sources for generating electricity. Vertical-axis wind turbines (VAWTs) are used in urban areas due to their advantages, with cross-flow wind turbines (CFWTs) being one type. However, the efficiency of CFWTs is relatively low, necessitating the application of augmentation devices. This study aims to find the optimal configuration between CFWTs and Omni-Directional Guide Vanes (ODGV), using 6DOF dynamic mesh methods in ANSYS Fluent with varying the turbine blade counts and the addition of ODGV. The results showed that the 18-blade configuration exhibits the highest improvement with ODGV, demonstrating a remarkable 71 percent increase in the power coefficient. In general, the highest performance is achieved by the 20-blade turbine with a 6-blade ODGV configuration, with a power coefficient of 0.2455, which is 30 percent higher than the baseline 20-blade turbine. These findings indicate that the addition of ODGV significantly improves the performance of cross-flow wind turbines.

Abstract

One of the materials that may be utilized in polymer matrix composites is high-density polyethylene (HDPE) plastic. Large amounts of HDPE plastic waste can harm the environment. Therefore, a solution is needed to overcome this problem. One solution to reduce plastic waste is to utilise it into polymer composite roof tiles. Roof tile surfaces are subjected to the greatest amount of solar heat radiation. This study aims to analyze the effect of variations in the composition of HDPE and teki grass on the value of solar radiation heat transfer and the value of thermal stability in polymer composite roof tiles. This research uses an experimental method by composites HDPE and teki grass with variations in the weight of teki grass used by 0%, 10%, 15%, and 20%. The results show that 20% teki grass composition in the composite produces low radiant heat compared to 0% teki grass composition which tends to be higher. according to the findings of the thermal stability test., The maximum thermal stability was seen in the composite with 0% fiber composition. While the most unstable composite is at 20% fiber composition with a 5% weight loss at 164.47oC and 10% at 278.27oC.
