molecular flow

For this to happen effectively, the pressure has to be in the region of free molecular flow.

In free molecular flow, the pressure of the remaining gas can be considered as effectively zero.

They repeated the molecular flow operation on the bronze and got rid of it.

The definition of a free molecular flow depends on the distance scale under consideration.

In fluid dynamics, the Knudsen equation is used to describe how gas flows through a tube in free molecular flow.

Neither the mechanism which produces the fast inner flows nor the evolution leading to the extended and slower molecular flows is understood.

A diffusion pump warm-up time of zero seconds is impossible in real life but used here for virtual Molecular Flow emulation.

Molecular Flow System Log An experimental monitoring system that will only be available when the system is running.

At higher (viscous flow) and lower (molecular flow) pressures, the thermal conductivity of air or any other gas is essentially independent of pressure.

-and profiles that have been observed in galactic molecular flows..." Hari nodded, raising a hand to slow the cascading words. "

When admitting gas or isotope mixtures under molecular flow conditions into a mass spectrometer for static analysis, fractionation and back diffusion occur unless equilibrium is reached.

The Molecular Flow Module is used for the simulation of vacuum systems including those used in semiconductor processing, particle accelerators and mass spectrometers.

Because turbomolecular pumps only work in molecular flow conditions, a pure turbomolecular pump will require a very large backing pump to work effectively.

In ending this article's molecular flow, there is only one thing we need to remember : when Pollock laid his canvas down, he laid Modernism to rest.

Experiments with the Molecular Flow System (MFS) require students to set up a constant gas flow into dome 3 and analyze the results.

The Cunningham slip correction factor allows predicting the drag force on a particle moving a fluid with Knudsen number between the continuum regime and free molecular flow.

Theoretical predictions were obtained for the effect of reflected nitrogen molecules on rotational temperature measurements with rocketborne electron beam fluorescence probes in the free molecular flow regime.

Molflow is a 3D DSMC simulator currently developed at CERN for the simulation of free molecular flow (vacuum) systems.

Free molecular flow describes the fluid dynamics of gas where the mean free path of the molecules is larger than the size of the chamber or of the object under test.

For example, in the interplanetary medium, the plasma is in a free molecular flow regime in scales less than 1 AU; thus, planets and moons are effectively under particle bombardment.

They were plowing through the thin air at a speed and height calculated to put them into what aerodynamicists call transitional flow, a state halfway between free molecular flow and continuum flow.

The ionization and thermal decomposition of tungsten π-cyclopentadienyl tricarbonyl dimer [WC5H5(CO)3]2 was investigated using a mass spectrometer fitted with single and double cell molecular flow inlet systems.

"Currently, the only mechanism known to produce such gap-crossing dense molecular flows, with residual carbon monoxide gas more diffusely spread out inside the gap, is planetary formation," lead scientist Simon Casassus of the University of Chile told Space.com in an email.

Invented in 1915 by Wolfgang Gaede using mercury vapor, and improved by Irving Langmuir and W. Crawford, they were the first type of high vacuum pumps operating in the regime of free molecular flow, where the movement of the gas molecules can be better understood as diffusion than by conventional fluid dynamics.
