  • 摘要:The main purpose of this research effort was to investigate and reduce the volume of thermal polluted cooling water from returning to the Kafr-Al-Batek power station. Traditional cooling systems, such as cooling towers or ponds can be very challenging with regards to implementation in developing countries; mainly due to the lack of financial capacity. This research focused on low-cost simulation solutions that could improve thermal outcomes. Comparisons were performed between three different scenarios to decrease the elevated temperature of the discharged water (43 °C) released by the Kafr-Al-Batek power station on the Damietta branch. The different scenarios were simulated by using Star CCM+ software. The base scenario examined the discharge angle of an existing outlet. The second scenario examined a new outlet downstream from the existing outlet. The third scenario increased the width of the existing outlet in order to reduce flow velocity. A comparative analysis is provided between the aforementioned solutions to identify the most suitable and cost-effective alternative. Simulation results show that changing the discharge angle from 90° to 135° is the most effective solution. Applying this solution has the potential to decrease the water temperature at the inlet by 7 degrees Celsius (from 32 °C to 25 °C).
