Investigation on the flow and heat transfer of supercritical CO2 in a semicircular channel under cooling conditions

Key Points

• Heat transfer efficiency is significantly influenced by flow characteristics in supercritical CO2.
• Key metrics indicate increased heat transfer rates at specific cooling conditions, reaching up to 15% higher efficiency.
• Analysis of flow behavior in a semicircular channel reveals unique patterns under supercritical conditions.
• Findings support the potential for enhanced cooling in thermal systems, leading to more efficient designs.
