A mathematical equation is a representation of natural laws or physical situations using mathematical symbols and operations to describe relationships between variables and their solutions. AI generated definition based on: Encyclopedia of Physical Science and Technology (Third Edition), 2003 ...
Starting from Boltzmann's equation, we derive a general system of transport equations using an approach that is valid for flow situations in which there are large temperature and drift velocity differences between the interacting species. However, this system of equations, which is obtained by ...
The mathematical equations The Fourier solution of the one-dimensional wave equation Today there is a string which is fastened to the two ends by a nail, and its initial displacement is: The initial velocity is 0, and we're trying to solve for it, where h is the known constant. Solution...
This equation enables us to ascertain the stationary measure of plastic in the sea if the pace of its vehicle to the sea is V, the underlying level of corruption is D0, and the consistency of the pace of debasement is k. The evaluations for poly hydroxybutyrate (PHB) plastic granules with...
In addition, a simulated orbit equation for saltation was derived. As compared with the actually photographied orbit the model is better than the saltation orbit simulated by former researchers. This paper first used the slippage movement concept, namely the particle movement patterns of vibration, ...
An analytical solution presented in a previous paper is incorporated into a numerical algorithm for determining water flow and solute transport in a single rectangular rock fracture with variable aperture and surface roughness. The flow is laminar and steady. Head and velocity are predicted analytically...
I am writing a small code to solve the laplacian equation over a 2D domain with a symmetry plane. The thing is that I am not sure what is the equation that holds for these nodes. I thought and probably is right that the equation is: du/dn = 0 ( homogeneus von Neumann BC). is ...
In this paper we determine the largest space in which the linearized compressible Navier-Stokes system in one dimension, with periodic boundary conditions, is stabilizable with any prescribed exponential decay rate, by an interior control acting only in the velocity equation. As a consequence, it al...
