Sentence examples for fast chemistry from inspiring English sources

The first two transactinoid elements, rutherfordium (Rf) and dubnium (Db), with atomic numbers 104 and 105, respectively, have isotopes with half-lives sufficiently long (13 and 32 hours, respectively) to allow determination of chemical properties by application of specifically devised "fast chemistry" techniques.

An eddy dissipation concept fast chemistry approach was used to account for the turbulence chemistry interaction.

Infinitely fast chemistry of Burke-Schumann formulation was employed to explain the combustion process.

In addition, these effects cause the leading edge position of the flame front to oscillate, even for infinitely fast chemistry.

The fast chemistry limit and thus the maximum flame temperatures are calculated using one-point equilibrium calculations.

The flow and mixing fields are calculated by assuming fast chemistry and a beta function pdf for mixture fraction.

In the gas phase, detailed chemical kinetics based on GRI3.0 and infinitely-fast chemistry are considered and compared.

A correlation was further established for the ratio of the turbulent hydrogen conversion rate at finite-rate chemistry to the corresponding turbulent conversion rate at infinitely-fast chemistry.

Up to now, simple models, like EBU, EDM/EDC, presumed PDF-fast chemistry models, are widely used in commercial software, but frequently give unreasonable results not agreed with experiments.

Results show that the flame stand-off distance predicted by the infinitely-fast chemistry model is shorter than the prediction obtained by the detailed chemical kinetics model and that flame stand-off distance using two-step model is longer than the CPD model.

It is shown that when neither the "fast-chemistry" nor the "slow-chemistry" approximation is satisfied, the overall burning rate is overpredicted.
