#### Abstract

Flow equations being nonlinear are notoriously difficult to solve analytically. In this work we show that through the three independent functions variational formalism for stationary barotropic flows one can obtain new analytical solutions of the flow equations. The flows are constructed such that they flow on predetermined Bernoullian surfaces from which the rest of the variational variables are derived. The flow obtained has non zero helicity.
