Thus, the final dimensionless form of the fluid phase momentum equation is dp∗ dx∗ = ∗ up∗ − B . (24) It is possible to substitute (17) into (24) to obtain a differ- ential equation describing the pressure as a function of the dimensionless distance x∗ . However, ...
neglect inertia in the momentum equation. The continuity equation (2) is fulfilled automatically when the stream function ψ is given by v 1 = −ψ z , v 3 =ψ x . (12) Then the underlying system can be transformed to a new form. After appli- cation of the curl-operator to ...
The device is a four-dimensional gyroscope, demonstrating the connection between the translational and the rotational inertia, which leads to the violation of the Momentum Conservation Law of the center of masses during its absolute elastic collision with the wall. For the proof of the violation of...

If the rigid microspheres underwent small levels of deformation and were subjected to a low load, their displacement and deformation satisfy the linear elastic momentum conservation (see the Equation (11)) and the governing equilibrium equation [23,24]. In this simulation, the Young’s modulus E...
The present formulae may then be used as a rigorous reduced-order model for validating higher-fidelity tools and complex simulations in industrial practice, as well as for estimating parametric sensitivities of unsteady aerodynamic loads within the preliminary design of aircraft wings in the subsonic ...
