Assessment of stress-blended eddy simulation model for accurate prediction of three-straight-bladed vertical axis wind turbine performance (2019)
Presentation / Conference
Syawitri, T. P., Yao, Y., Yao, J., & Chandra, B. (2019, March). Assessment of stress-blended eddy simulation model for accurate prediction of three-straight-bladed vertical axis wind turbine performance. Paper presented at 54th 3AF International Conference on Applied Aerodynamics

The performance of a three-straight-bladed vertical axis wind turbine at low tip speed ratio has been evaluated by detached eddy simulation (DES) with stress-blended eddy simulation (SBES) turbulence model. Two grid topologies around the blades, i.e....

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.

Computational study of a customised shallow-sump aero-engine bearing chamber with inserts to improve oil residence volume (2017)
Presentation / Conference
Adeniyi, A., Chandra, B., & Simmons, K. (2017, June). Computational study of a customised shallow-sump aero-engine bearing chamber with inserts to improve oil residence volume. Paper presented at ASME Turbo Expo 2017: Turbomachinery Technical Conference and Exposition

An aero-engine bearing chamber is a structure that is used to contain and collect oil used in lubricating and cooling the bearings supporting the high-speed engine shafts. There are various bearings in an aero-engine. Within the bearing chambers, the...

Innovative shallow sump customizations for aero-engine bearing chambers (2016)
Presentation / Conference
Chandra, B., & Simmons, K. (2016, June). Innovative shallow sump customizations for aero-engine bearing chambers. Paper presented at ASME Turbo Expo 2016

Aero-engines incorporate various bearing chambers and these typically contain bearings, seals, rotating shafts, stationary walls and struts, and sometimes gears. Oil is supplied for lubrication and cooling and is removed (scavenged) from the sump reg... Read More about Innovative shallow sump customizations for aero-engine bearing chambers.
