Improvement on pressure distribution for venturi tube flow

A goal driven optimization process has been undertaken for a venturi tube. Venturi tube create a constriction within a pipe that builds backpressure upstream and effects a negative pressure downstream of the constriction. The passage of a fluid through a constriction, causing a pressure drop and inc...
