SVS Experiment Specs - Spray Nozzle Virtual Laboratory System

Available parameters for experiments and display of results

1. Available parameters

(1) Two optional spray patterns

Flat spray
Flat

Full cone spray
Full corn

(2) Optional uniformity rate of flow density graph
Three optional uniformity rates: 30%; 50%; and 80%.

Uniformity rate (%)= Uniformity width / whole spray width x 100

(3) Spray angle in SVS experiments
In actuality, the outermost droplets flowing from a nozzle to the target surface do not travel in a straight line due to various factors, including gravity, spray distance, pressure, and nozzle type. For the purposes of SVS experiments, however, calculations are made theoretically on the assumption that the spray angle is stable, as shown in the illustration below. When determining nozzle configuration, therefore, more accurate results can be obtained by specifying spray distance and spray width rather than spray angle.

(4) Detailed specifications of nozzle
Enter specifications, such as pressure, flow rate, spray angle, etc.: the SVS will perform a virtual experiment.

(5) Your preferred nozzle configuration
Enter your preferred dimensions in the plumbing drawing provided. The SVS will perform a virtual experiment based on the configuration you specify.

2. Display of results

(1) View an animated simulation of the spray configuration you specify

(2) View your spray array from any viewpoint simply by moving your mouse

(3) A flow density graph can also be generated from your specifications (About the graph)

(4) The uniformity rate of the flow density of your specified configuration will be calculated automatically.

SVS virtual experiments are offered under the following conditions:

The animated spray pattern produced herein should be regarded as a visual approximation of reality.

Flow density graphs and uniformity rate are based on theoretical values defined by NNC, and should be regarded as being for informational purposes only.

The information displayed herein does not apply to any specific nozzle nor to any particular manufacturer's products.

The sprayed fluid is assumed to comprise a single liquid (water).
