Journal Article
STOUT, C., ISLAM, S., WHITE, A., ARNOTT, S., KOLLOVOZI, E., SHAW, M., DROUBI, G., SINHA, Y. and BIRD, B. 2017. Efficiency improvement of vertical axis wind turbines with an upstream deflector. Energy procedia [online], 118: proceedings of the 2nd International conference on advances on clean energy research (ICACER 2017), 7-9 April 2017, Berlin, Germany, pages 141-148. Available from: https://doi.org/10.1016/j.egypro.2017.07.032

The suitability of using an upstream deflector to improve the efficiency of a vertical axis wind turbine is presented in this study. A two-dimensional vertical axis wind turbine (VAWT) was modelled and simulated using ANSYS Fluent 14.0 computational...

A prognostic decision model for offshore wind turbines maintenance. (2015)
Journal Article
SINHA, Y. and STEEL, J.A. 2015. A prognostic decision model for offshore wind turbines maintenance. Wind engineering [online], 39(5), pages 569-578. Available from: https://doi.org/10.1260/0309-524X.39.5.569

Frequent unscheduled random maintenance activities have significantly increased the operating cost of Offshore Wind Turbines (OWT). These activities account for ∼65% of the overall OWT maintenance costs or 23% of the lifetime costs of OWT, equivalent...

Failure prognostic schemes and database design of a software tool for efficient management of wind turbine maintenance. (2015)
Journal Article
SINHA, Y. and STEEL, J.A. 2015. Failure prognostic schemes and database design of a software tool for efficient management of wind turbine maintenance. Wind engineering [online], 39(4), pages 453-477. Available from: https://doi.org/10.1260/0309-524X.39.4.453

Wind Turbines require numerous and varied types of maintenance activities throughout their lifespan, the frequency of which increases with years in operation. At present the proportion of maintenance cost to the total cost for wind turbines is signif...

A progressive study into offshore wind farm maintenance optimisation using risk based failure analysis. (2014)
Journal Article
SINHA, Y. and STEEL, J.A. 2015. A progressive study into offshore wind farm maintenance optimisation using risk based failure analysis. Renewable and sustainable energy reviews [online], 42, pages 735-742. Available from: https://doi.org/10.1016/j.rser.2014.10.087

Offshore Wind Farm consists of an array of Wind Turbines electrical, communication, command and control systems. At present the cost of maintaining Wind Turbines in the offshore locations is very high (about 35% of lifetime costs). This work puts emp...

Significance of effective lubrication in mitigating system failures: a wind turbine gearbox case study. (2014)
Journal Article
SINHA, Y., STEEL, J.A., ANDRAWUS, J.A. and GIBSON, K. 2014. Significance of effective lubrication in mitigating system failures: a wind turbine gearbox case study. Wind engineering [online], 38(4), pages 441-449. Available from: https://doi.org/10.1260/0309-524x.38.4.441

The effectiveness of lubrication in machines mainly depends on the physical and chemical properties of lubricating oil, like quantity, level of suspended particles, effect of external load/shear forces, temperature amongst others. Periodic inspection... Read More about Significance of effective lubrication in mitigating system failures: a wind turbine gearbox case study..

A SMART software package for maintenance optimisation of offshore wind turbines. (2013)
Journal Article
SINHA, Y., STEEL, J.A., ANDRAWUS, J.A. and GIBSON, K. 2013. A SMART software package for maintenace optimisation of offshore wind turbines. Wind engineering [online], 37(6), pages 569-577. Available from: https://doi.org/10.1260/0309-524X.37.6.569

Offshore Wind Turbine (OWT) maintenance costs in between 20 - 35% of the lifetime power generation cost. Many techniques and tools that are being developed to curtail this cost are challenged by the stochastic climatic conditions of offshore location...
