TAILIEUCHUNG - Low-head hydropower energy resource harvesting: design and manufacturing of the (HyPER) harvester
The design and manufacturing of a revolutionary hydropower harvester with characteristics that embrace the ecology and the environment is described. Guided by NEPA standards for environmental protection, the design concept incorporates a modular and self-supporting structure with a vertical-axis turbine-generator system that is: a) fabricated using Fiberglass and Carboncomposites and is light weight, and b) is easy to manufacture and assemble utilizing offthe-shelf electromechanical components and deploy to produce the desired power. | SCIENCE & TECHNOLOGY DEVELOPMENT, , - 2015 Low-head hydropower energy resource harvesting: design and manufacturing of the (HyPER) harvester Nadipuram R.

(Manuscript Received on July 15, 2015, Manuscript Revised August 30, 2015) ABSTRACT The design and manufacturing of a revolutionary hydropower harvester with characteristics that embrace the ecology and the environment is described. Guided by NEPA standards for environmental protection, the design concept incorporates a modular and self-supporting structure with a vertical-axis turbine-generator system that is: a) fabricated using Fiberglass and Carboncomposites and is light weight, and b) is easy to manufacture and assemble utilizing offthe-shelf electromechanical components and deploy to produce the desired power. A computational fluid dynamics (CFD) software, ANSYS®, is used to optimize the flow characteristics of the harvester. A fullyscalable, modular and easily deployable hydropower generating system prototype of a 10kW low-head hydropower harvester with 4blade fixed-pitch impeller is presented. The technology is adaptable for low-head drops along irrigation canals with existing structures and as modular weirs across small rivers and streams worldwide. Keywords: computational fluid dynamics, harvester system, low-head Venturi turbine, turbine impellers. 1. INTRODUCTION As a cause and effect phenomena, the misuse of natural hydropower resources and the irreversible damage to the ecology, strongly direct the imaginations and creativity of engineers and scientists to focus on technologies that will allow future generations to coexist in energy-efficient, self-sufficient, energy conserving, and selfsustaining environments. In Vietnam, for example, as much as 40% of electric power comes Trang 132 from hydropower plants. The .
