Momentum-energy is fundamental: its conservation governs every collision in the universe, and it is also frame-invariant, remaining the same regardless of the chosen frame of reference.
The time dependent conservation equations governing the flow fields are transformed to dimensionless form using the non-dimensional parameters.
More rigorously, Boltzmann showed that it is possible to proceed from the conservation laws governing molecular encounters to general statements, such as the distribution of velocities, which are largely independent of how the molecules interact.
Above all, it brings forward a set of conservation equations governing the mean flow of both phases of a suspension in the continuum approximation.
Nonpremixed ignition of counterflowing H2 against hot air is studied numerically with emphasis on developing simplifying approximations to the conservation equations governing this system.
Where natural gas not subject to State regulatory or conservation laws governing its purchase by pipelines is offered for sale, each such pipeline shall purchase, without discrimination, any such natural gas produced in the vicinity of the pipeline.
The present model simplifies the complete conservation equations governing the IFR system by utilizing the assumptions that the initial IFR coating layer (virgin plus melt) is thermally thin and its expanding char layer, which includes also the vapor and the foam, has negligible volumetric heat capacity.
Due to the approximation accuracy, momentum conservation and governing equation feasibility, traditional Particle Method, Moving Particle Semi-implicit (MPS) method in this paper, cannot guarantee the accuracy and stability of computation, and the divergence calculation in Navier Stokes equation may cause numerical error in computation domain with discontinuity.
In cases in which there appear to be no conservation laws governing the explanatorily relevant property (i.e., cases in which the explanatorily relevant variables are not conserved quantities) this difficulty seems even more acute.
The two men have had long conservations about governing.
