Thereby, a mathematic model was developed to predict the two-phase pressure drop across the Laval nozzle. The pressure drop model described the experimental data within the 15% deviation. The main influence factors contributing to the pressure drop of the Laval nozzle were discussed using the ...
thereby adjusting the combining tube to nozzle gap. As the combining tube/nozzle gap is widened, the pressure drop is lowered. As the gap is narrowed or closed, the pressure drop is increased. The pressure drop is measured between the inlet and the discharge of the slurry connections on the...
In the attached example, we have a 6” nozzle connection on the tank and our calculations according to API 2000 resulted in a required flow for this tank application (see later for sizing) of 1250 m3/h. Let’s assume we have determined a safe maximum pressure of 15 mbarg, which is ...
The slit would represent an opening all across the width of the device and the pressure drop would be lower than obtained in the physical experiments. The applicability of the porous media flow theory to provide additional pressure drop across a nozzle can be explored as a remedy to this ...

The turbine is decomposed in its main parts (namely, the nozzle, the stator, the rotor, and the diffuser), and for each one a system of governing equations is solved. Each system of equations is composed by: the first law of thermodynamics; the continuity equation; the ideal gas law and...
an erosion test was conducted. This pilot test was carried out to determine the optimal standoff distance between the PWJ nozzle and the workpiece material. The standoff distance corresponding to the deepest generated groove was selected for the main experiments. With the selected water pressure, ...
