Hypersonic Heat Transfer Rate Calculator

– Hypersonic and High-Temperature Gas Dynamics, John D. Anderson, Jr.

This formula calculates the heat transfer rate to a surface in hypersonic flows, which is essential for understanding thermal loads on the surfaces of high-speed vehicles. High-speed flows generate significant heat due to air compression, and this equation helps in managing thermal protection.

Symbols:

• q: Heat transfer rate per unit area
• ρ: Freestream density (kg/m³)
• V: Freestream velocity (m/s)
• Ch​: Stanton number (dimensionless)
