knudsen number उदाहरण वाक्य

उदाहरण वाक्य

1. The Knudsen number can be used to guide the choice between statistical mechanics and the continuous formulation of aerodynamics.
2. Airflow around an aircraft has a low Knudsen number, making it firmly in the realm of continuum mechanics.
3. His name is associated with the Knudsen flow, Knudsen diffusion, Knudsen number, Knudsen layer and Knudsen gases.
4. The Knudsen number helps determine whether statistical mechanics or the continuum mechanics formulation of fluid dynamics should be used to model a situation.
5. This requires the Knudsen number to be small, as is also a pre-requisite for the continuum hypothesis to be a valid one.
6. Additionally, rarefied hypersonic flows ( usually defined as those with a Knudsen number above 0.1 ) do not follow the Navier Stokes equations.
7. Problems with high Knudsen numbers include the calculation of the motion of a dust particle through the lower atmosphere, or the motion of a satellite through the exosphere.
8. Statistical mechanics can also describe work in non-linear dynamics, chaos theory, thermal physics, fluid dynamics ( particularly at high Knudsen numbers ), or plasma physics.
9. Physical systems with Knudsen numbers at or above unity require the use of statistical mechanics, which itself provides the underlying physics of fluids which is an input to fluid mechanics.
10. Problems with Knudsen numbers below 0.1 can be evaluated using continuum hypothesis, but molecular approach ( statistical mechanics ) can be applied for all ranges of Knudsen numbers.
