ππ¨ Updated Simulation Prompt for WINDURJA (with Side-Mounted Vertical Turbines) Simulate the wind energy generation potential from vertical-axis wind turbines (VAWTs) mounted at the mirror positions on both sides of a moving passenger train. The train is traveling at a constant speed of 90 km/h (25 m/s) on a straight track. Two vertical-axis wind turbines, each with a 0.5-meter diameter and 1-meter height, are installed symmetrically at the positions typically used for rear-view mirrors, just outside the driver's cabin area on both sides. Simulation Requirements: Use Computational Fluid Dynamics (CFD) to analyze airflow behavior around the turbine due to the trainβs movement. Evaluate the effective wind speed and flow pressure hitting the turbine blades at mirror position. Include aerodynamic effects from the train body β air deflection, turbulence, and flow compression around the mounting point. Estimate the power output using the wind power formula: π = 0.5 β π β π΄ β π£ 3 β πΆ π P=0.5β Οβ Aβ v 3 β C p β Where: Ο = 1.225 kg/mΒ³ (air density) A = swept area of turbine (mΒ²) v = wind speed in m/s Cβ = power coefficient (~0.35 for small vertical turbines) Simulate energy output over a range of speeds (60β120 km/h) Consider energy conversion losses (~25%) for practical estimation Environment Setup: Train type: Standard electric or diesel passenger train (can assume a streamlined body) Altitude: Sea level Weather: Neutral (no external wind; only wind generated by train movement) Surface condition: Smooth railway track Simulation Goals: Visualize airflow hitting the turbines at mirror positions Identify optimal mounting angle or slight offsets for maximum energy harvest Estimate the energy output per hour (in Watts) Show feasibility of powering AC, fans, and lights using this method while reducing load on traditional power sources
