Piping Systems FluidFlow3 - Dynamic Analysis & Scripting

Scripting can be an effective tool when you are ready to expand your design capabilities. Considering design scenarios, design optimisation, safety and operating studies are an essential part of achieving quality, well designed flow systems.

Writing a script using either the Basic or Pascal language enables you to change any network or element property and watch what will happen. You can see a video here that shows how 2 control valves adjust to speed changes of a centrifugal pump.

Today energy conservation should be a vital part of all your designs. Click here to see a video that considers how to minimise energy consumption during operation of a pump station containing 5 pumps.

We are able to offer Scripting help as a service. To get your project off to a flying start, please contact sales@excelatcad.com directly and we will provide individual advice.

Control Valve Turndown [1m 32s]

Scripting allows you to change any property of any network element and then watch the response of any other property. In this example we change the speed of a pump and watch how flow control valves respond as well as watching the pump duty point adjust on the pump performance chart.

Pump Optimisation [40s]

In this example we will find the optimum pump operating speed if we run 5 pumps in parallel. The optimium speed depends on the number of pumps operating and can be markedly different. We will run a script that asks how many pumps we wish to run. The script solves the system for a series of pump speeds ranging from the minimum to maximum operating speed. Results are exported to Excel (Flow, Speed, and Power needed per kg of fluid pumped). Finally, the script plots an excel chart, so we can see easily where the optimum speed lies.
