FAQ

What is local heat-transfer rate using Nusselt's number?
The local heat-transfer rate using Nusselt's number formula is defined as the ratio of the product of Nusselt's number, thermal conductivity at the edge of the boundary layer and difference of adiabatic wall temperature and wall temperature to the distance along the wall measured from the leading edge and is represented as qw=(NuD*k*(Taw-Tw))/(x) or Local heat transfer rate=(Nusselt Number*Thermal Conductivity*(Adiabatic wall temperature-Wall temperature))/(Distance from the nose tip to required base dia). The Nusselt number is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection and diffusion. The conductive component is measured under the same conditions as the convective but for a hypothetically motionless fluid, Thermal Conductivity is the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance, 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 is the temperature at the wall and Distance from the nose tip to required base dia, used for studying the leading edge of the hypersonic vehicles.
