Heat Transfer Rate in aircraft design refers to the rate at which thermal energy (heat) is transferred from one region or component to another within the aircraft. This parameter is crucial for managing and controlling temperatures in various systems and components to ensure safe and efficient operation.The formula for heat transfer rate and its SI unit are as follows:
Heat Transfer Rate Formula: The formula for heat transfer rate (Q) is based on the principles of heat transfer and can be expressed as:
- Q: Heat Transfer Rate, measured in watts (W) or kilowatts (kW).
- U: Thermal Conductance, representing the material’s ability to conduct heat. Measured in watts per square meter per Kelvin (W/(m²·K)).
- A: Surface Area through which heat is transferred, measured in square meters (m²).
- ΔT: Temperature Difference between the hot and cold regions, measured in kelvin (K) or degrees Celsius (°C).
