21. This is an implicit relation that determines the solution of the inviscid Burgers'equation provided characteristics don't intersect. 22. It can be shown that the virtual mass force, for a spherical particle submerged in an inviscid , incompressible fluid is 23. An alternative way would be to calculate the deflection angle at which the boundary layer subjected to the inviscid pressure field separates. 24. Although in this case we have assumed an inviscid fluid this assumption does not hold for flows where there is a boundary. 25. In practical aerodynamics, the displacement thickness essentially modifies the shape of a body immersed in a fluid to allow an inviscid solution. 26. In high Reynolds number flows, the flow is often modeled as an inviscid flow, an approximation in which viscosity is completely neglected. 27. Obviously this Jacobian does not exist in discontinuity regions ( e . g . contact discontinuities, shock waves in inviscid nonconductive flows ). 28. Inviscid flow is governed by the Euler equations for which there are many simple solution methods depending on what specific assumptions can be made.29. In this case, the inviscid flow around an airfoil can be approximated by a potential flow satisfying the no-penetration boundary condition. 30. His inviscid theory of these currents did not have a time invariant solution; no simple solution to this problem has ever been found.
