Although such flow patterns can be, in principle, described by the Navier-Stokes equations, extracting the velocity and pressure fields directly from the images is challenging. We addressed this problem by developing hidden fluid mechanics (HFM), a physics-informed deep-learning framework capable of...
These problems include the compressible Euler equations in fluid mechanics, the Vlasov equation in plasma physics. These methods have been extended to non-purely convective problems, to take into account diffusion effects. This has first been done by addition of a random walk to the movement of ...

Fluid metals around normal density can be thought of as low temperature non-ideal plasmas. They are plasmas in that the Coulomb interactions among the constituent particles are important in determining thermodynamic and transport properties. They are low temperature in that even up to 1 eV the temp...

It is one of the fundamental concepts in classical mechanics that considers the motion of bodies. If you want to put this rule down in the form of a mathematical formula, the velocity equation will be as follows: velocity = distance / time Keep in mind that this velocity formula only ...
