kinetic theory

n.
A theory of the thermodynamic behavior of matter, especially the relationships among pressure, volume, and temperature in gases, based on the dependence of temperature on the kinetic energy of the rapidly moving particles of a substance. The theory uses statistical mechanics under the presumption that energy and momentum are conserved in all collisions between particles.

When considering the kinetic theory as applied to an ideal gas (see Jeans [19]), any of the associated results are inherently linked to the conditions which gave rise to the ideal gas law.
They employed models typically used to study gases consisting of a large number of molecules that collide at random (known as thermostatted kinetic theory) to study the consequences of the different interactions occurring among pedestrians in a crowd while exiting a metro station.
This assumption about initial state is intrinsic for the kinetic theory, because in this case all possible states of gases are described by means of a one-particle distribution function.
In the simulation of a dense fluidized bed, the discrete particles are approximated as continuous phase for describing the gas-particle and particle-particle interaction, which is based on the kinetic theory of granular flow (KTGF).
Traditional stability methods are based on the application of mathematical models that come from the kinetic theory of gases to wide variety of liquid, semisolid, and solid drug products.
The number of recent past theories, such as the germ theory, the special theory of relativity, the kinetic theory, and evolutionary theory, is far larger than the number of distant past theories, such as the humoral theory, the ether theory, the caloric theory, and the phlogiston theory.
After setting out the foundations, they cover Bose-Einstein condensation, quantum kinetic theory, quantum matter waves, ultra-cold molecules and scattering, ultra-cold Fermions, and atoms in optical lattices.
A typical theoretical model for the particle concentration distribution is given by Wang and coworkers using the kinetic theory for two-phase flow [14]:
In this article, therefore, the kinetic theory of granular flows (KTGF) is still used to close the viscosity and pressure of the solid phase, neglecting the effects of structure on the stress tensor, and the gas viscosity is assumed to be constant.
I found, while teaching mechanics of continuous media, elasticity, and fluid dynamics, my students listened eagerly as I told them something about atomic structure of the materials and kinetic theory of gases.
Moreover, it is shown that the structure is compatible with the moment series expansion of kinetic theory, at least up to the third moment [15].
