Unformatted text preview: flow, necessarily their cross product is zero. Therefore, f vortex = for Beltrami flow (b) For steady Beltrami flow, u / t = 0 , and the vortex force is zero, so that the Euler equation simplifies to w 1 2 u u W = p V If the flow is also incompressible, is constant so that all terms can be grouped together in parentheses as follows. w p + 1 2 u u + V W = Therefore, the quantity in parentheses must be constant, viz., p + 1 2 u u + V = constant...
