Assessment of the oil scoop capture efficiency in high speed rotors (2018)
Journal Article
Paleo Cageao, P., Simmons, K., Prabhakar, A., & Chandra, B. (2019). Assessment of the oil scoop capture efficiency in high speed rotors. Journal of Engineering for Gas Turbines and Power, 141(1), 012401. https://doi.org/10.1115/1.4040812

© 2019 by ASME. Experimental research was conducted into a scooped rotor system that captures oil from a stationary jet and directs it through passages within the shaft to another axial location. Such a system has benefits for delivering oil via unde... Read More about Assessment of the oil scoop capture efficiency in high speed rotors.

A review of current technical development in vertical axis wind turbine technologies and their braking system for low speed, urban and offshore areas application (2018)
Presentation / Conference
Syawitri, T., Yao, Y., & Chandra, B. (2018, October). A review of current technical development in vertical axis wind turbine technologies and their braking system for low speed, urban and offshore areas application. Paper presented at International Conference of Global Warming and Climate Change 2018

Recently, there are growing interests of using Vertical Axis Wind Turbine (VAWT) to harvest wind energy from low wind speed in urban areas to relatively high wind speed in offshore wind farms. Horizontal Axis Wind Turbine (HAWT) has been known to hav...

CFD simulation of three-straight-bladed vertical axis wind turbine at low tip speed ratios (2018)
Presentation / Conference
Syawitri, T., Yao, Y., Chandra, B., & Yao, J. (2018, October). CFD simulation of three-straight-bladed vertical axis wind turbine at low tip speed ratios. Paper presented at International Conference of Global Warming and Climate Change 2018

This paper presents computational fluid dynamics (CFD) simulations of a three-straight-bladed Vertical Axis Wind Turbine (VAWT) operating at a wind speed of 9 m/s and low Tip Speed Ratio (TSR) ranging from 1.44 to 3.3. The turbine blade has NACA 0021... Read More about CFD simulation of three-straight-bladed vertical axis wind turbine at low tip speed ratios.

Mechanisms for Residence Volume Reduction in Shallow Sump (2018)
Journal Article
Chandra, B., Simmons, K., & Murphy, A. (2018). Mechanisms for Residence Volume Reduction in Shallow Sump. Journal of Engineering for Gas Turbines and Power, 140(3), https://doi.org/10.1115/1.4037871

© 2018 by ASME. Gas turbine aero-engines employ fast rotating shafts that are supported by bearings at several axial locations along the engine. Due to extreme load and heat, oil is injected to the bearings to aid lubrication and cooling. The oil is... Read More about Mechanisms for Residence Volume Reduction in Shallow Sump.
