Digital Twin

eDART Flow Analysis

By using 1-D (Flownex) and 3-D (floEFD) flow simulation packages, eDART is able to create a digital twin of the system around the valve. This is really useful when scoping a project and understanding how all the elements of a system interact with each other. The benefit is that eDART products work.

Below are a number of products where we have had great success:

Back Pressure Pipe

eDART Back Pressure Pipe In a mineral concentrator the crushed ore is passed through a cascading system of floatation machines. eDART valves are located between each cell to control the flow and are subjected to the pressure drop which is a function of the height between the two, aeration in both, vertical head and density change should there be any feed introduced to the process, however on the last cell there is a significant pressure drop across the valve. Back pressure pipes, otherwise known as goosenecks or riser pipes, are used in this case to represent another cell so the valve does not have to be specially designed for this increased pressure drop. The resulting reduction in step for the last cell before the sump can be used to reduce the overall height of the bank or allow for another piece of equipment to be used like a metallurgical sampler.

Centre Pipe Sampler

The continuous centre pipe sampler and surrounding is modelled here. The great advantage is that all the parameters like roughness and heights can be checked for sensitivity and we then know where to concentrate. eDART centre pipe sampler digital twin

Distribution/splitter boxes

eDART distribution/splitter boxes eDART models the inlets and outlets of distribution and splitter boxes to optimise the design and get good mixing and even flow from the outlets. Good box design will often have a dropbox in the inlet chamber to cushion the inlet flow if fed from the top, an underflow weir to the boiling chamber and an overflow weir which can be split easily to achieve the desired output.
