Experimental and numerical solution of formation and evolution of cavitation in laval nozzle
Original language description
Contribution presents experimental equipment applied for formation and evolution of cavitation in Laval nozzle. In detail the equipment design including nominated measurement of basic physical quantities as pressure and flow rate is described. The regionof cavitation formation and evolution for various operating conditions is evaluated using digital exposure series. In the second part of paper the multiphase mathematical model of cavitation in program ANSYS Fluent12 is defined and applied for computational region of Laval nozzle using the same boundary condition as in experiment. Results of numerical simulation are compared with experimental measurement. Furthermore the design of experimental equipment is extended in air saturation design of water including flowmeter design for determination of saturated air amount.
