How does the change in thermal conductivity of the gas (say Air and Helium) affect the cooling rate, in the absence of magnetic field?

06 June 2013 1 1K Report

Take the velocity of the gas as very high (900m/s).

Article Effects of thermal conductivity on unsteady MHD free convect...

In your abstract you write: "It is assumed that the thermal conductivity of the fluid as a linear function of temperature." My understanding is that thermal conductivity of the fluid is proportional to the square root of temperature - see my paper: "SHOULD ENGINEERING THERMODYNAMICS INCLUDE A SIMPLIFIED TREATMENT OF ITS UNDERLYING MOLECULAR BASIS?" page 10
