Evolution of the average cluster size at the center of a cluster jet from the nozzle throat along the gas flow is investigated using simulations. The simulation is performed for the cluster jet from the expansion of Ar gas into vacuum through a long conical nozzle (with the length L of 30 mm) under a high backing pressure (similar to 5 x 10(6) Pa)....
This work aims to understand the cluster size deviation from the prediction by an existing scaling law for conical nozzles. The dimensions of cluster jet at different heights above a nozzle along the direction of gas flow are measured. This study indicates that the dimension of cluster jet is underestimated in the existing scaling law and this unde...
Using Rayleigh scattering measurement, we experimentally studied the effect of the opening angle of conical nozzles on the average sizes of argon clusters produced by high-pressure argon gas (up to 50 bars) expanding into vacuum. Both the scattering signal intensity and the scattering image were synchronically recorded by a photomultiplier tube and...
