Hi,

Do you know if there is a way of knowing what the thermal conductivity of a gas mixture is in posdat?

Regards

Hi , I ma trying to find out the thermal diffusiviy of a mixture of air and diesel. Do you know any calculating procedure by thermal conductivity, density a and cp using?? thank you for answering me

A commonly used mixing rule is to multiply each property by the components mass fraction & sum them together. So for example

mixture density = air mass fraction * air density + fuel mass fraction * fuel density.
