and the other with a stagnation point flow, i.e., ( x 1 d ln ⁡ ⁡ a 1 / d t , x 2 d ln ⁡ ⁡ a 2 / d t , x 3 d ln ⁡ ⁡ a 3 / d t ) . Particularly, the physical meaning of Λ Λ can be seen to be attributed to the uniform-vorticity motion. The pressure is found to assume a quadratic form, as derived by the equation of motion (and using the vanishing condition at the surface) given by
