Measurement of the Influence of Roof Pitch to Increasing Wind Power Density

Abstract

The wind flows on the rooftop house in Semarang, Indonesia past were examined in a Computational Fluid Dynamics (CFD) analysis and indicate best performance for wind energy power density. The rooftop pitches of house can have huge impact on increasing wind power density. This paper deals with the study to increase wind power density of micro-wind turbine located on the rooftop house by design the roof pitch. CFD was performed to evaluate the performance of wind flow around the roof pitch of housing at different angle (20 o , 30 o , 40 o and 50 o ) based on wind climate data analysis. The results showed that a pitched roof of 30 o has the best wind potential density than another for same base house model height.
