A review on small scale wind turbines
TL;DR: In this paper, the performance, blade design, control and manufacturing of horizontal axis and vertical axis wind turbines are reviewed based on experimental and numerical studies and lessons learnt from various studies/countries on actual installation of small wind turbines were presented.
Journal ArticleDOI
Effect of airfoil and solidity on performance of small scale vertical axis wind turbine using three dimensional CFD model
Abhishek Subramanian,S. Arun Yogesh,Hrishikesh Sivanandan,Abhijit Giri,Madhavan Vasudevan,Vivek Mugundhan,Ratna Kishore Velamati +6 more
TL;DR: In this article, the effect of solidity and airfoil profile on the performance of VAWT was studied using ANSYS Fluent four different airfoils (NACA 0012, NACA 0015, AIR 0030 and AIR 001) with an incoming wind velocity of 10m/s.
Journal ArticleDOI
Numerical study of effect of pitch angle on performance characteristics of a HAWT
A R Sudhamshu,Manik Chandra Pandey,Nivedh Sunil,N S Satish,Vivek Mugundhan,Ratna Kishore Velamati +5 more
TL;DR: In this paper, the effect of pitch angle on the performance of a horizontal axis wind turbine was investigated using a commercial CFD code Fluent, where a frozen rotor model is used for simulation, wherein the governing equations are solved in the moving frame of reference rotating with the rotor speed.
Journal ArticleDOI
Investigation on supersonic combustion of hydrogen with variation of combustor inlet conditions
TL;DR: In this article, the effect of variation in the inlet Mach number and stagnation temperature on the mixing of fuel with the oxidizer and the subsequent stabilization of a flame in a combustor at supersonic conditions was numerically investigated.

Numerical Analysis of Effect of Pitch Angle on a Small Scale Vertical Axis Wind Turbine
R Bose Sumantraa,S Chandramouli,T P Premsai,P Prithviraj,Vivek Mugundhan,Ratna Kishore Velamati +5 more
TL;DR: In this paper, the effect of preset pitch angle on the performance of a three-bladed H-Darrieus VAWT has been considered for the study and the equations governing the flow are solved using a commercial CFD code ANSYS CFX 13.
