In addition to having high thermal conductivity, TIMs are expected to be robust with respect to environmental and ambient conditions, reduce thermal stress between two regions with very different coefficients of thermal expansion, have low viscosity at operating temperature, have a long working life ...
Transport coefficients of high-temperature nitrogen The electrical conductivity, the translational, reactive, and internal thermal conductivity and the viscosity have been calculated for nitrogen at 1-atm pressure and temperatures from 5000-35 000掳K. Generally satisfactory agreement is n... Capitelli,M...

For fibrous materials, these results provide more evidence that the temperature-dependence is mainly determined by the air viscosity. Measurements on AES at 20掳C indicate negligible change in the specific airflow resistance when measured with flow velocities between 0.5 10 3 and 1.83 10 3 m/s ...

The dissipation of the energy of sound waves attributed to the medium in which they propagate, in this case air, is caused by three mechanisms: shear viscosity, thermal conductivity, and molecular relaxation. These represent different processes in which sound energy is converted into heat or intern...
n = gas viscosity r = radius of the airway Since resistance is inversely proportional to the radius to the fourth power, anything that changes the radius or diameter of the airway will tremendously affect resistance to airflow. For example, if bronchoconstriction as a result of asthma or airwa...
