High-rise elevator shafts behave like aerodynamic tubes, and when a high-speed elevator car moves through them, it acts like a piston. This video explains the physics behind the Piston Effect—how the moving cabin compresses air, how pressure builds ahead of the car, and why turbulence, noise, and vibrations increase as speeds exceed 3.5 m/s and 6 m/s in dual-shaft configurations.

We explore:
• How pressure zones form above and below the cabin
• Why airflow becomes turbulent inside sealed shafts
• The impact on door operation, ride comfort, and speed performance
• The role of fairings, door sealing, and shaft ventilation
• How advanced control systems prevent simultaneous movements that intensify the effect
• Engineering strategies to balance pressure and ensure smooth vertical transportation in supertall buildings

Understanding the piston effect is essential for designing next-generation high-rise elevator systems with improved comfort, stability, and safety.
