Variables Used
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
Local Heat Transfer Rate - (Measured in Watt per Square Meter) - Local Heat Transfer Rate, is that energy per second per unit area.
Distance from Nose Tip to Required Base Diameter - (Measured in Meter) - Distance from Nose Tip to Required Base Diameter, used for studying the leading edge of the hypersonic vehicles.
Nusselt Number - The Nusselt Number is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection and diffusion.
Adiabatic Wall Temperature - (Measured in Kelvin) - Adiabatic wall temperature, is the temperature acquired by a wall in liquid or gas flow if the condition of thermal insulation is observed on it.
Wall Temperature - (Measured in Kelvin) - Wall Temperature is the temperature at the wall.
