| Summary: | Francis turbine is kind of water turbine which using spiral case to guide water flow into the runner. Spiral shape is needed to keep uniformity of water velocity in runner inlet. <br />
<br />
<br />
Spiral case design in this research are special for welded construction process (segmented spiral case). <br />
<br />
<br />
This final project is focused on investigate conical spiral shape because spiral segments are produced by rolling process. Rolling process only can produce two shapes, cylindrical and conical. There are three criteria to compare some of spiral shape, function, manufactureability, cost. <br />
<br />
<br />
Literature study from spiral case modelling in previous design, then making new modelling to solve problems from that design. <br />
<br />
<br />
Final result of this project is how to design and modelling spiral case with high manufactureability. |
