wind tunnel 3d model

Small wind tunnel energy setup with correct airflow direction: 1) An axial fan pushing air forward (not pulling), like a desk fan. 2) A short honeycomb flow straightener placed after the fan, made of straight parallel hexagonal tubes (not mesh), aligned with airflow. 3) A smooth contraction nozzle after the honeycomb to increase air velocity. 4) A 3-blade horizontal-axis wind turbine on a stand, placed after the contraction. All components aligned in this order: fan → honeycomb → contraction → turbine Include visible spacing between parts and clear left-to-right airflow direction. Style: realistic engineering prototype, clean design, neutral colors. Wind tunnel setup: a fan pushing air forward, followed by a short honeycomb of straight tubes, followed by a narrowing nozzle, then a 3-blade wind turbine. All aligned in one direction with visible spacing. Engineering prototype style.
