Turbulent thermal conductivity () refers to the effective thermal conductivity of a fluid when it is experiencing turbulent flow. Thermal conductivity is a property that quantifies a material’s ability to conduct heat, representing the rate at which heat is transferred through the material due to a temperature gradient.
- is the turbulent thermal conductivity,
- is the turbulent eddy viscosity of the fluid,
- is the specific heat capacity of the fluid at constant pressure,
- is the turbulent Prandtl number.
