| Summary: | This thesis consists of research regarding a new system of harnessing
hydropower energy that utilises product development process methodology,
computer-aided drawing software, and computational fluid analysis software as
the platforms to conduct fluid dynamic analysis on the product development. The
objectives of this research is to develop an alternative hydropower harnessing
method for Malaysian river applications. In this research, a working prototype for
the generator unit that will be used in the new method is developed. The product
development process includes doing prior research, information gathering,
concept generation and evaluation of the concepts via a qualitative concept
selection process. The main parts of the prototype are designed using CATIA
version 5.2, analysed using ANSYS version 16.0, manufactured via 3D printing
and the 3D printed turbines field tested in local rivers. The product development
process resulted in concept 2 being chosen to be developed further. From the
ANSYS analysis, experimental and field test data, turbine runner with curved
blades proved to perform better than straight blades at an average of 41%
difference. Further ANSYS analysis done on generator arrangement shows that
the turbines will perform at a maximum efficiency roughly around the value of X,
Y and Z at 500 cm. The results shows that the prototype has a good potential to
be able to generate power while operating in a relatively small site. The new
method also possesses the characteristics to be less environmentally intrusive
than the conventional hydropower method, with significantly less assumed costs
due to its operating size and easier maintenance. This research will be able to
contribute towards powering areas with constant flowing rivers, especially
isolated areas where common power grid cannot access. To conclude the
project, a further recommendation for future works is proposed to perfect the
system and improve its efficiency and practicality. |
