I'm not an expert in CFD. But based on my limited knowledge and experience, the applications are listed below.

• Aerospace: Simulating airflow over aircraft wings to optimise wing shapes for improved lift-to-drag ratios, enhancing fuel efficiency and performance.
• Automotive: Simulating the cooling systems of electric vehicle batteries to ensure optimal thermal management and prevent overheating.
• Energy: Simulating combustion processes within gas turbines to optimise air and fuel flow for higher efficiency and lower emissions.
• Healthcare: Simulating blood flow through stenosed arteries to assess the risk of plaque rupture and inform treatment strategies.
• Environmental Engineering: Simulating the dispersion of pollutants from factory smokestacks to evaluate environmental impact and guide mitigation efforts.
• Marine: Simulating ship hull hydrodynamics to reduce drag and improve fuel efficiency.
• Electronics: Simulating airflow within data centres to optimise cooling strategies and minimise energy consumption.
• HVAC: Simulating airflow in cleanrooms to ensure effective ventilation and contamination control.
• Materials Science: Simulating the flow of molten metal in casting processes to predict defects and optimise mould designs.
