USING CFTURBO PART 2

Last week we edited the meridonal contour and today we're going to continue designing our pump by editing the blades. We click blade properties button and in this window we can set the number of blades and spans. Spans will be used to curve the inlet and outlet of the blade at different heights. 

Then we can edit the blade lines and its angles. We could even design a Barske type impeller combining some parameters.

Click OK and we can go on editing the blade profiles. To add  rounded edges go to Freeform and select LE rounded to round the leading edge and TE rounded to round the trailing edge. 

With the following window you can set the edge position but just click OK and go to the next step.

In this window we are not going to make any changes, so just click OK.

Now we are going to create a volute. Click the sum sign on the outlet, then click New volute.

 A window will appear. There you can choose wether you want a single or a double volute and you can also define some dimensions. Unless you disable the automatic update, the volute dimensions will be automatically recalculated in case the interface values are modified. Click OK and continue.

In the next window you can select a desired shape for the volute. It could be symmetric or asymemetric in case you want to. You can also select different shapes along the volute by creating sections. Once it's done, click OK and continue.

In this window you can modify the contour of the volute. 

This window is used to design the diffuser. You can modify its direction and shape. Click OK and in the next window click OK.

Then go back to the impeller and click CFD setup. Select Extension option and Extention outlet at r=constant. Under RSI conection title, select Outlet option.

Finally click the flag and select Solid Trimming and click OK+Run. This week I'll also publish the CFD simulation of the pump.
